Potential bug with Kalista's Auto-attack

Playing Kalista in the PBE I noticed that due to her auto-attack animation her attack speed (to me) doesn't seem to mirror or truly represent what you build. For instance, at 2.5 attack speed, Kalista seems to attack slightly slower than that due to her lengthy animation, except when attacking dragon, baron, or towers. Attacking those objects her animation seems to provide no hindrance, but minions, monsters, and champions she seems to attack far slower than one would expect. Just something that may need to be looked into. Thank you RIOT and fantastic work by the way. The new map, jungle creeps, and all around the new additions are splendid. Thank you so much for all your hard work. It was well worth it.
