First off, I would like to apologize if this topic has already been started with the intent of a similar discussion; the search feature is absolutely broken - or I have lost all wits and should just quit now - so I was unable to find out whether or not this has been discussed. If so, a link would be appreciated so we can expand upon a topic already broached by another.
I have spent some deal of time looking through all the Epic Destinies and the different abilities offered by each one, and a larger deal of time looking at each of their respective 'capstone enhancements' so to speak - in other words, their tier 5 main active abilities - which for the purpose of this post I shall call EDC (for Epic Destiny Capstones). I couldn't help but notice the very extensive cool-down that is tied with the Exalted Angel EDC which happens to be my main destiny as I play a healing and light damage based Favored Soul character. The cool-down seems quite disproportional when compared to the other EDCs. Each of the others require a 5 minute cool-down, while the Primal Destiny EDC only requires a 5 second cool-down; so why should the Exalted Angel EDC require 30 minutes to be reused.
The first logical conclusion on the greatly increased cool-down would be that this EDC offers a much higher level of power and thus must be limited due to balance issues. At a first glance of the description, this seem *almost* fair, as it leads one to believe that upon using you are fully healed, gain +100 to light and healing power, immunity to light damage, 50% incorporeality, spell duration is reduced to 1/5th normal, and spells cost 50% less to cast.
This seems fairly powerful, but really no more so than the Primal Avatar which gives massive amount of bonus damage per attack; I've seen heal-bots use this EDC and hit 500+ easily with a trash weapon. However under closer examination, the underlined portion of the effects above is only gained if used when dead, instantly excluding nearly any character from gaining these effects - who wants to die just to get a few bonuses?
So thus you only get a +100 to light and healing power, immunity to light damage, 50% incorporeality: worthy effects for the most part, but not deserving of a 30 minute cool-down when compared to the Primal Avatar EDC which gives a massive damage boost, and the Fury of the Wild EDC which also gives massive boosts, while they have cool-downs of 5 seconds and 5 minutes respectively. And for those who believe the lengthened cool-down comes from the defensive part of the EDC, then please take the time to view the EDC for the Draconic Incarnation line: 5 minute cool-down for a 30 second DR 100/epic, resistance 200 to elemental damage, and a swift hit point regeneration effect. Yes, this is only for 30 seconds, but only 20 enemies must be damaged by a Evocation of Conjuration spell in order to use. 1 cast of Cone of Cold can easily fulfill the requirements.
The 30 minute cool-down of the Exalted Angel EDC is way overblown. 30 minutes is rarely enough time to use it more than once in the average quest, while when raiding you may only get the chance to use to once or twice. I would like to hear others opinion's on the matter and if they think it should be reduced and why. As for myself, I believe this cool-down completely destroys the functionality of this EDC and should be reduced to the normal cool-down of 5 minutes, giving back its worth of two Epic Destiny points. As is, it is a complete waste of two points and very few casters use this ability.
