The whirlwind was supposed to hit at low range or to hit minions or monsters that are further away to blink to an enemy that is airborne from other means. But yeah, 3 seconds is too much, so I'll make it get reduced by level.

For the bow, It's there to make it easier to last hit (as he should be weak early game, maybe I need to change some numbers to achieve that) and even to make him viable in the bot lane. He is supposed to get into melee range to kill people. But I think you may be right and I put too many weaknesses in this ability, so I will reduce them.
