I like the idea of stun not lasting as long. 3 rounds max is what it should be. That would be so perfect. Making veil of ice last longer would also be a great thing. I also liked the channeling idea.
Okay, so after a long new york minute I'm semi functional on the computer side of interaction....I like your post sir.
I also seem to be making yet another crappy formatted post or potentially trollish post, however this one isn't aiming for humor and is trying to be helpful....
I'ld honestly give the feedback consider removing veil of ice. Make iceskin (guild spell if i recall correctly) an optional legend rank. Give iceskin (as legend rank purchase) half durability/duration of iceskin to all and make it AURA / divine. You might need to actually quarter it but as I remember iceskin's duration is a bit long so maybe shave half the duration off iceskin's base off the top (prelegend), so that legend halving of it would be appropriate.
In terms of nerfing stun, I'm of the sort that kinda expects it to be gone, yet will miss it even though I don't have it. However veil of ice absolutely sucks (maybe not so much with 8-14 slots and autohaste and magical unicorns and ponies dancing atop a perfectly microwaved burrito).... It's never memmed or casted when it would save lives, and when it is casted it's always a waste. Even a fixed 1-2 tick duration on it would be better than the "This spell lasts 2-3 pulses or up to 8 seconds" current reality.
