Remove Deathcap, add more ap items
I went through the list of every ap carry in the game. Every one of them builds a deathcap. What could be more boring than a big ball of one stat on an item you need on all apcs every game? Whenever I play mid, I build the exact same 5 items over and over again (morello, sorc, void, dcap, zhonya) on every champion, occasionally switching something out for roa/tear/lich bane for short range/spammy/autoattack modifier mages. Meanwhile every game as a tank I look at opponent builds. Playing as adc, I can build apen and flat ad and sheen upgrades on caster adcs, and full crit on auto-reliant adcs. Or go for on-hit effects.
