AS for last hitting?
Been searching for info on this, but unfortunately most hits on google are really old and I'm not sure how things have changed. I am wondering about the viability of using AS runes for last hitting. The reason I don't test it myself is because it's going to be a long time before I have enough IP for that.
Obviously using AD gives a larger window for last hitting, and is used by most people including pros. But is there any reason to use AS over AD? For example, I'm finding that the enemy will be poking the hell out of me and sometimes I have to choose to get 1 cs or possibly lose half my health and have to retreat completely, losing multiple CS. A faster attack speed would allow me to get in, last hit, and get out much more quickly. It could also allow better last hitting under the turret by being able to prime the minions more quickly and beat the turret's shot. With AD, yes the window is larger, but with the slow base level attack speed I leave myself open to being poked for far longer. With AS runes, I can cut that time in half. It also allows for more poking on my part.
Does this sound reasonable? Has anyone tried this approach and what were the results?
instead of attack speed, because he is an ad caster assasin, so he scales much better with flat ad than attack speed.
