Haste and cast times

[Jervaise]

Greetings dear Paladins, could anyone enlighten me on how much haste is required to cast holy light in approximately 2 seconds with raid buffs excluding DI?

cheers!

Edit: I actually would be more interested in a proper list of haste rating and cast time of holy light. Radiance is easy to find on most sites, however in my search I couldn't find one for holy light.

Thanks once again

There are no lists because the only cast which benefits from haste on certain levels only is HR => lists for other spells are completely pointless.

For 2 seconds casttime you'd need 25% haste which would be 774 rating raidbuffed. (this number has no meaning just sayin)

Base cast time = 2.5
Wanted cast time = 2
Base haste = 1.03*1.05*1.09 = 1.178835
Rating needed per percentage haste = 128.05716

Rating = Ceiling((2.5/(2*1.178835)-1) *12805.716) = 774 rating

Which is the same as the haste needed for 13th tick of HR.

Thanks, a paladin friend of mine was very interested on this for reasons I don't know. We were testing it for an hour or so but couldn't come up with the exact number. Info is appreciated

On my hunter when i wanna figure out what cast speed my steady shot/cobra shot will have i use this: 2.0 / (1.1 * 1.03 * 1.15 * (1 + ((YOURHASTERATING/128.057)/100))

And what you do is, change the first number to the base cast time (steayd/cobra is 2 sec) then inside the parentheses you add up all the different places you will get haste from, so on my hunter that would be 10% haste from frost dk/WF totem/ Surv hunter, 3% from talents and 15% from Improved Steady shot. and then you just type in how much haste rating you have and paste that in to google and it will figure it out for you.

Hope that makes sense as im quite tired atm.

On EJ you'll find some more usefull information on this topic.

The formula for Holy Paladins is:

Haste_Needed = (Base_Cast_Time / Desired_Cast_Time / (1.03*1.05*1.09) -1 ) * 12812.5

For Holy Light Base_Cast_Time is 2.5 so you need (2.5/2/1.178835-1)*12812.5 = ~774 Hasterating

EDIT: To clarify: The Product 1.03*1.05*1.09 contains of all Haste-Modifiers, which come not(!) from gear, as Speed of Light (1.03), 5%-Haste Buff from Moonkin, Shadow, Shamy (1.05) and JotP (1.09).

Easy

2.5/2= 1.25


You need 25% more haste BUT you already have 17% of haste via talents and buffs so you need only 8%.

1% haste = 128.0576 haste rating

So

128.0576*8= 1024.4608 ---> 1025 haste rating

No, haste is multiplicative.

You need 25% haste. You start with 3%, 5%, and 9% from talents and raid buffs.

1.03*1.05*1.09=1.178835

1.25/1.178835 = 1.06036892

You need 6.04% from gear.

6.04*128.0576 = 773.467904

You need 774 haste rating from gear. As stated in the first reply to the OP.

774 is way not enough. I got 1630 (12.73%) haste and my casting time raidbuffed is 1.93. All the information I can find are that 1% haste is 128.11 haste and it's exactly accurate in my case, so you need 8% which is 1024 haste. Please do some basic maths before making your own assumptions and driving people into confusion.

So I buy something someone has put up for sale and ... I'm a thief? Nice logic.

BS! Whether you have 5% or 25% haste it will always come up 128.11 per 1% when you divide them.

Haste stacks multiplicative...

So your Haste in percent is: (1 + Haste_on_Gear / 12812.5) * Haste_Modifier_1 * Haste_Modifier_1 * ... * Haste_Modifier_n

The exact formula for Holypaladins with all buff, except DI and buffs like DF, BL, SoW-OnUse, etc, is what I postet above.

It derives as followed:

Haste_Percent_Needed = (Base_Cast_Time / Desired_Cast_Time - 1) * 100
Haste_Rating_Needed = (Haste_Percent_Need / 100 + 1) / Product_Haste_Modifiers * 12812.5
Haste_Rating_Needed = (Base_Cast_Time / Desired_Cast_Time) / Product_Haste_Modifiers * 12812.5

So yes, with the 17.8835 percent Haste from buffs you need only ~6% from gear (1.25/1.178835), not ~8% (25%-17%). And ~6% are ~774 Hasterating.

Same with HR and additional ticks.
For the first tick you need only 5% Haste, any other additional ticks needs 10 more percent.
So for the 13th tick you need 5+10+10 = 25% => ~774 Hasterating
For the 14th tick you need 35% => 1.35 / 1.178835 = 1.1452 (~14,5%). This is equal to 0.1452 * 12812.5 = ~1860 Hasterating

If Haste was additiv, you'll need 35%-17,8835% = 17.1165% => ~2193 Hasterating

Premise: Haste stacks additively from multiple sources, thus at 1024 haste rating with 5% spell haste buff, 3/3 Speed of Light, 3/3 Judgements of the Pure, Judgements of the Pure active, and no haste cooldowns, the cast time of Holy Light is 2.00 seconds.

See the album (http://imgur.com/a/5VwcK#0) for evidence of these numbers:

456 haste = 2.05 sec cast time
943 haste = 1.98 sec cast time
2027 haste = 1.83 sec cast time

At 456 haste, the cast time is OVER 2.00 seconds. At 943 haste the cast time is UNDER 2.00 seconds. This means the cast time is 2.00 seconds at some point between 456 and 943 haste.

1024 is not between 456 and 943.

Reverse logic:
At 943 haste, the cast time is 1.98 seconds. At 2027 haste the cast time is 1.83 seconds. Thus at any value of haste between 943 and 2027, the cast time MUST be between 1.83 and 1.98 seconds.

1024 haste is between 943 and 2027, but 2.00 seconds is NOT between 1.83 and 1.98 seconds. This means 1024 haste cannot possibly correspond to a cast time of 2.00 seconds.

To rephrase and clarify:
At 943 haste, the cast time is BELOW 2.00 seconds. As haste increases, cast time decreases. This means that for any value of haste above 943, the cast time must be less than 1.99 seconds.

1024 haste is greater than 943, so the cast time at 1024 haste must be LESS THAN 1.99 seconds, so it cannot be 2.

Those are (or 'that is a', if you look at those as the same argument) perfectly valid proof that your understanding of haste is flawed. It absolutely doesn't stack additively from multiple sources, it is multiplicative

P.S. The idea of haste stacking additively annoys me, you may have noticed.
