This has been discussed quite a bit but for the people who say SW
is useless they really dont understand math terribly well.
1. SW
costs 1 GCD
2. MF (full duration will always cost 2 GCDs)
3. 2 ticks of MF > 1 GCD
4. 1 tick of MF < 1 GCD and therefore not terribly effecient.
Assuming 11.11% haste
1. SW
costs 1.35 seconds
2. Full duration MF costs 2.7 seconds
3. 2 Ticks of MF costs 1.8 seconds
4. 1 Tick of MF costs 0.9 seconds but a 1.35sec GCD is still enforced.
Therefore when you compare 2 ticks of MF to 1 SW
you are conviently ignoring the 0.45sec difference in cast time which in most circumstances directly delays your next MB cast. This also assumes you clip MF exactly on time which I doubt is humanly possible without making any mistakes. I would argue that you would clip MF at 2.0 seconds on a regular basis. I would then suggest that 2 clips of MF results in delaying your MB cast by 0.65 seconds, the MB spell cycle is equal to 1.35 (cast) + 5.5 seconds (CD) = 6.85 seconds, therefore dealying it by 0.65 seconds amounts to a 9.5% delay. I would estimate you need to make a decision what to do with 1 GCD every 3 cycles so you potential miss out on casting 3% of your Mind Blasts using this strategy.
SW
on the other hand fits into the GCD perfectly, there is no issue about trying to clip the spell meaning you can pretty much queue the next spell instantly. SW
is higher dps until you reach a certain level of gear, and even when it becomes slightly less DPS than MF it won't delay your MBs. So until the dps of MF > SW
+ the loss of MB dps by casting 2 ticks of MF, SW
is still a viable spell to use.
Can I point out for the last time... simcraft using SW
in the rotation as higher dps than no SW
. I concede the dps gain is almost insignificant but it shows that the statment "SW
is lower dps" is illinformed at best. My personal opinion is that it's ok to use SW
(when used properly) and its just as ok not to use it... it comes down to personal style but as simcraft points out, either strategy arrives at nearly exactly the same number. If you want to be technically correct, SW
is 11 more dps than no SW
(from the top of my head, results are posted in simcraft).
