Ehm I can just say a few things about this...

wtf? So true damage on all abilities after you scale W and I don't feel like this champion will have any mana problems after RoA or something like that (tear etc).

As TDT said your Q will have lower CD than the mark duration so in theory you do have permanent true damage and there is no way to counter outright true damage...

Well you need to put more thought into this... not put the first ability you can think of that could fit. I don't see the synergy of this kit and most of your abilities are overloaded. Heck the W is basically a level 2-3 powerspike which eliminates any mana problems after you get tear/RoA/other mana item.

I think you would want to adjust the power of this champion from way too consistent true damage at 750 range, no mana problems at all to actually give it some weaknesses except for no mobility, which is kinda irrelevant mid-late as nobody is going to step close to you.
