Runes, masteries, and paying for a champion are the big ones.Warding is much harder in League because there is no high ground to hide them on and the truesight item has no risk/reward. The fact that every champion who is expected to initiate needs to have a built in skill for it rather than just buying a blink dagger. Putting spells crucial to fights on 5 minute cooldowns. Flash being available at level 1 for anyone makes level 1 agression impossible. The fact that melee carries practically don't exist because there is nothing like a bkb.

I could go on about pettier things but I'll leave it here.
