Lee's Q is one of the only non-DoT basic abilities left in the game that deals 320+ base damage.
And that's on top of the high-end scaling/execute it has.
Just FYI.
######It deals 340; Blitz's is the next closest at 300, IIRC.
######Edit: Nid's spear is 390 at max range; keep in mind that's much less reliable as well.
Max range Javelin toss is 390
