1. Spell bar upon casting:
As the most discussed and frustrating issue on sorcerers, this is by far (in my opinion) the thing that needs the most attention regarding to this class since I think its one of the main reasons that sorcerers arent being played that much.
Upon clicking to cast a spell, the first thing that happens is to load the spell bar AND THEN the animation starts and actually performs. This is bad enough on its own and adding the fact that were locked down this whole time, makes it almost impossible to hit and run from anything or anyone especially with some of the spells that take so much time to charge.
I think there is only ONE REAL problem with Sorceress (and with Shadowmage too, since that problem is shared with both classes) and that problem is the "Animation Lock" you described.
On many games i played there was the animation chained with the CHANNELING ONLY. This mean that after the channeling is done, the mage is free to move.
What i mean?
[That is what should happen]
Channeling + Animation
Cast + Cooldown
[That is what happen NOW]
Cast + Animation
That is wrong. Point.
On the first example the situation is that:
Channeling is 1s long, Cast is 1s long = Skill is exactly how it's wrote: 2s casting (1+1)
On the second one, that is what NOW happen the situation is that:
Channeling is 1s, Animation is 1s long, Cast is 1s long = The skill is not 2s casting (1+1) but 3 seconds.
Other than that, i think there aren't other problems.
