@RIOT Please decide whether Ezreal's Q is an auto attack or a spell

So according to League Wiki his Q does the following.

Does not apply spell effects. Mystic Shot will apply on-hit effects as a ranged attack, including life steal, http://vignette3.wikia.nocookie.net/leagueoflegends/images/c/c6/Sheen_item.png/revision/latest/scale-to-width-down/20?cb=20130319091454 , and the reduced slow fromhttp://vignette3.wikia.nocookie.net/leagueoflegends/images/a/ac/Frozen_Mallet_item.png/revision/latest/scale-to-width-down/20?cb=20130319090339. Mystic Shot cannot critically strike. Mystic Shot will not affect structures. Mystic Shot's damage will be mitigated if the attack is http://vignette4.wikia.nocookie.net/leagueoflegends/images/6/66/Counter_Strike.png/revision/latest/scale-to-width-down/20?cb=20130929122859 dodged, http://vignette2.wikia.nocookie.net/leagueoflegends/images/d/de/Riposte.png/revision/latest/scale-to-width-down/20?cb=20150721193218 parried, http://vignette1.wikia.nocookie.net/leagueoflegends/images/d/d7/Aegis_Protection.png/revision/latest/scale-to-width-down/20?cb=20130929123145 blocked or misses. http://vignette1.wikia.nocookie.net/leagueoflegends/images/0/03/Banshee%27s_Veil_item.png/revision/latest/scale-to-width-down/20?cb=20130319090152 Spell shields will block the damage.

So it doesn't interact with Deathfire Torch or Sorcery masteries but is blocked by "spell shields". Why not give it reduced crit damage like that scales with CDR or something along those lines.

I just think it should treated completely as an auto attack or be treated entirely as a spell instead of 60% auto attack 40% spell.
