Thank's for critical dude :)

With 180 AD with full build, a crit is only hitting, what, 450? Half off that for armor is 225. With max AS thats 500 damage per second, with 0 survivability. I like the idea that you switch later in game into an AD carry, but it is not good if you dont buy more items. You should sell things like Nashors tooth lategame for a bloodthirster.

On another note, you are using the wrong form of "to" in your title. It should be, LuLu AD is too stronk; just saying lol.

I'd recommend frozen mallet and a bloodrazor. These items are stronger on on-hit champs then an IE at that point.
