its funny tho, i would have gladly taken a dmg nerf to fel flame and keep its resource generation as is, coz they seem to want to nerf movement dps, instead they went the other way. now the question is, will fel flame for destro still have an obscenely high mana cost or not, 25% mana seem a bit excessive for WoD assuming we actually get it back.
the thing that has made me the most upset is that our core soulburn abilities all got a shardcost increase which is going to be a pain to manage and the side effect is that they have made any version of soul swap worthless to use coz any version only allows you to save 1 gcd for each soul shard you use which is a waste of shards, there are plenty of other ways to get the job, and now without snapshotting, which was the main reason soul swap was so good, there was no real reason to change it.
