So, do I have to build my Yi glass cannon in order for him to do damage D: I try to build Tanky w/ Frozen Mallet, Maw of Malmortius and whatnot but my damage drops dramatically Mid-Late Game and I'm not even that Tanky >.>
I'm also considering buying Gragas; thoughts? I don't know how to play / build him though. Do I just poke with Q and whatnot in teamfights and use E as only an escape? Or do I build him a bit tankier so I can use E for damage as well? :/
Yi: In my opinion, Yi is best when he's built tanky deeps, since he actually survives long enough to do some real damage instead of three-shotting one guy then dying, plus, add a Wriggle's or a Bloodthirster to that, and it really synergizes well with your Maw since your AD (and thus, your healing-per-hit with Lifesteal) goes up as you get lower.
Gragas: In teamfights, Gragas should be using his E for damage. It's on a super-short cooldown, and his W gives him a buff that provides massive damage reduction. Keep in mind that you should never, EVER voluntarily cancel a channel on your W, since that buff is what makes you such a good champion. Also, get REALLY well-acquainted with how your R works, since otherwise you'll be saving enemies all the time by accident.
