Bolt Escape is now useless. You've completely broken the ability.
So congratulations on listening to a bunch of whiney people on the internet and destroying a class defining ability.
There's ways you could kinda fix this. You could immediately remove the 50% increase in cost on subsequent casts. You could remove the 4 sec magicka regen debuff. Keeping both active is just ridiculous and just ensures no intelligent player will ever use this ability.
Really what you should do is remove both the 4 sec magicka regen debuff and the 4 sec subsequent cast penalty. The ability was perfectly balanced already. The utility you got was commensurate with the cost of the skill and there were plenty of ways to get the same thing from other sources. There were plenty of counters to the ability as well. Not to mention you've promised that this game would have no cool downs and this ability now has TWO cool downs.
But I'm learning that you guys don't really care about balance, truth, ect. You don't know how to differentiate the good feedback from the bad. The only way to get things done is to have a lot of ignorant/misinformed people complain really loudly on the internet. God forbid you listened to people who Beta tested your game, who spent hours doing actually testing (not just playing and whining.)
You seem to have kinda sorta thought about it. You changed "Dark Deal" so that you could move while channeling it. This seems like an attempt to make up for the survivability hit that you gave to the sorcs. Problem is you move really slowly while channeling Dark Deal, so you might as well be stationary. You also removed the armor and spell resistance buff and kept it interruptable, so you're still a sitting duck.
I'd recommend a mix of the following changes:
-Increase movement speed while channeling Dark Deal
-Make Dark Deal uninterruptable
-Give the caster increased armor and spell resistance while channeling Dark Exchange (both morphs)
But hey, unless I get 50 people to complain about it on Reddit and the general forums (preferably without them making a single intelligent point about why the changes would be good) then you probably won't listen.
