Don't use forums much, but I can already tell this is probably going to be at least the 50th Khazix thread.
Okay, so I have had some bad games lately. Last game my team won but I had like 6/3/18, bottom laner, with Morde, Garen, Rengar, and Kog'maw, and I focused on HP items including Frozen mallet. I forget the team before that but I got completely snowballed under with the same character, focusing on AD items.
My questions are these, how do you know how to balance between HP and AD items? Should you take HP if you're steam rolling, or should you take AD to keep that damage up? Finally, when/at what point would be a good signal to follow your team in at team fights? I get lucky if I can burn down even one champ in a team fight before they all focus on me and kill me when I attack with my team.
