Would be cool if they'd just let us choose which skill effects to have. Could call it a skill-glamour or something. Personally I don't like Stone, but I think if others do like it, they should be allowed to reach back into their kit and use that animation over the Glare we have now. Same with old holy, etc.
More weight would be welcomed in general. Skills in this game feel really floaty and light; I can't stand it.
