Olaf Q visibility problems

Few days ago I played Olaf and really liked his style of gameplay. One thing I didn't like, however, was Olaf's Q. Olaf's Undertow is a very fine ability imo, but esp. during team fights its hard for me to see them and pick them up. Olaf's gameplay is dependent on picking up his axes. So I suggest, Riot, that the game shows me the exact location of the axes by using arrows like Katarina's daggers. (This is only my opinion, you may agree/disagree)
