What if Annie's passive gave her abilities different effects?
As opposed to just a stun, I mean.
Here's some examples of things I can think to put on each spell:
Q: Either a lowering of the target's stats (MR or Armor or both?) or maybe damage amplification, like a smaller, shorter DFG active W: AOE slow thats kind of high at low levels, but not too great late game E: Give non-passive molten shield a speed boost (like Tibbers), and the passive version an even larger one? Or maybe she puts a shield (and speed boost) on an ally? R: Keep as a stun
Why remove the stun from all of Annie's abilities? Well, I think it would make her less annoying to play against for one (point and click stuns aren't cool yo), as well as free up some of her power budget to make her a but more interesting to play.
Im not saying she's a problem really. I love playing Annie personally. I just thought I'd share some ideas I had to add a bit more diversity to her kit while making her less of a pain to deal with.
