Beatnik pointed most of my problems out. Mana drain is not fun, I'd turn it into a health drain, but you pay upkeep for it, or something like that. Also, too many percentageceptions there (percentage of percentage of something). Try to make it more flat. Example: Vlad's Q deals flat damage that is reduced by MR. It also heals him by a flat amount that doesn't change based on the damage you deal. Very simple. Fiddle's drain heals you a percentage of the damage you deal. That's a little more complex, and a little more logical, I'd say. At one point there you said something like "Costs 15% of current mana, damages for 80% of the cost, roots for 0.1 per 70 mana used to cast and gives MR equal to 10% of the damage dealt." I'm good at maths, but this is just too complicated to figure out. Making it, idk, 15% current mana, taking the median of the possible mana you could have (e.g. 2k, 3k, something), and instead of having 80% of the cost, make it flat 200 or something. And MR by flat 20.

I might have it a little wrong (which actually proves my point), but the thing is, you have too much calculus there, which isn't even that vitally important. Simplify, then yes.

Btw, she's a tank/support. Drain keeps her mana and shit up while her shield keeps her alive and her other stuff helps protect your team and aid it.
