Some math on q and e. First of all, q will match e's dmg starting at both of them being lvl 2, which means in the jungle especially, you are better off with leveling Arcane Smash after getting rank 1 of Sappling Toss at lvl 1. In lane you have to hit both the on hit and the explode EVERY TIME for it to come close to the same amount of damage, and you get much less damage per mana.

CDR does not affect this table's ratios at all but AP does. Arcane Smash gets 40% of your ap and technically Sappling Toss gets 100% because of the 2 hits at 40 and 60. But it takes a whopping 200 ap for these abilities to even out. Which means Sappling Toss wont be better even with ap until late game, so again, leveling it first is not a good idea.

I did vote up your guide, I just wanted to point out this one thing that bugged me :P

my table is all nicely lined up in the post but when it actually goes up, its all scrunched...


btw, @Douleur
Thornmail is good vs AS champions while Frozen Heart is good vs AD champions.

Thornmail takes off dmg of the attack itself (because of armor) and gives some of it back to them. When being attacked repeatedly and quickly you will mitigate a ton of damage. While with a heavy AD champion (or a crit champ) you will not be mitigating as much because they don't attack as often, you only get any less damage taken and damage reflected when you actually get hit. So for these champions you want frozen heart, which slows down their attack speed even more and mitigates damage by preventing the attack from happening all together, or at least delaying it.
