you just look like a nub building full hp runes and level sequence wrong and i checked your tristana build even worst

I agree with the post above me and not only that, I noticed that your ability level sequence is completly outa wack...your feral scream totals up to 6 points and your vorpal spikes add up to 4, which for those who actually play LOL know that it's seemingly impossible to have over 5 points in any given ability.

Also, within your talent tree you get the "Menders" talent, but you dont have the summoner spell too which it would be usefull...

Hate to break it to ya but soulstealer's dont get you HP they get you AP and the max you can get from leviathin is 640 HP and 940 from feast that adds to about 4500 HP if you get to 20 stacks. Thats the tuff part, getting all those stacks oly gaining 32 HP per stack thats kinda week until about 15 stacks but you need to be a beast cho for this build to work, sorry but i dont see this going anywhere.
