Tier 1: Speed of Light
In my opinion, this talent stands out as a poor alternative to the other two talents in this tier, which both give speed boosts with a massive difference in uptime and overall benefit. The following is a Paladin's aggregate run speed using Judgement and Speed of Light on cooldown, and with an average of 1.5 holy power, over 1 minute to simulate all disregard for "stacking" holy power to improve Pursuit of Justice's speed effect.
Speed of Light: 109.33%
Pursuit of Justice: 125%
Long Arm of the Law: 122.5%
So, Speed of Light's aggregate effect over the duration of its cooldown is lower than that of the other two talents, which both have high uptime and similar results. I personally don't think 8 seconds of insane speed make up for 52 seconds of zero benefit. I would like to see Speed of Light also include "Increases your speed by 20% during the last 50% of Speed of Light's cooldown and when this ability is not on cooldown." With this change, a Paladin with Speed of Light experiences an aggregate run speed of 119.33%. I feel like this average speed is a good number, considering with this talent a paladin also gets the nice 8 second sprint effect.
Tier 4: Hand of Purity
In my opinion, I feel the reasons why this talent is sub-par are somewhat obvious. Either this talent needs a longer duration to be viable or scrapped altogether, although a longer duration could make the talent too useful in PvP while still being sub-par for PvE(and if 1 or more fights don't include DoT effects.. then what?) I love the concept this ability presents and I think there is an opportunity for it to become a full-time, non-talented hand spell that could see some niche uses, but with the current amount of non-dispellable DoT's present in PvE, I just can't see it worth being taken over a Cold Snap for our Hand spells and a reduced CD on our major mitigation tools. Something has to be done, even if I cant think of any good suggestions that keep the overall talent idea intact. As it stands, this talent is just a watered down hand of Protection that, while debatably being an interesting tool in a Paladin's arsenal, doesn't match up to the other two talents in this tier.
I love the other talents we have access to, and I believe each tier is balanced well, save for these two talents, and I believe some semi-major fixes need to be introduced in order for these talents to become on par with others in their tiers. Do you think any other paladin talents are sub-par, or need work? Do you believe the 2 talents I singled out need work in the current talent tree? What are your ideas for fixes for these talents and others?
