I recently started playing as Cho'gath top lane (I used to play him when i first started out because of how simple his kit is). I have a few other top laners such as Darius, Fiora, Lee Sin, and others. I love being the tank for my team. One thing I cannot figure out is, which is more important, hp, or armor/mres? I usually end a game with a Randuin's Omen, Warmog's, and ocasionally a Frozen Heart and Sunfire cape (depending on the game length). Any tips/tricks for tanks?
