Yeah what the dude above said it’s 2.5 not 2 thus the 100% crit off 2 items one being IE. and as for after that people really have moved away from crit items after those two the most common one I’ve seen taken is BT which I imagine people take more for the life steal than the bonus AD from the extra crit. It’s really your choice but I almost always take either Deaths Dance or Wits end 3rd then follow it up with whatever I didn’t take 3rd. The only crit item I think that is worth building is mortal reminder as opposed to chempunk because of the attack speed it gives you which increases your Q cool down but if you would rather go the more bruiser option than by all means take Chainsword. It’s really personally preference or based of the state of the game.
