Why must you constantly have Ashe free? Yes shes a beginner hero but, in my honestly opinion, she is very OP and very cheap. I feel if a beginner truly tried Ashe and did well, then tried another hero, they would get annihilated and get a false sense of superiority when playing Ashe. Like the fact that if Ashe hits you once, and you run away she will always catch you, due to the fact that you are constantly being slowed. If Udyr's stun can only be performed every 5 seconds, her slow should do the same if not longer.
Her Ultimate should also be like Ezreal's in that it gets weaker as it passes through creep waves. I think Ashe is a hero that should not be 450, she's way too OP. I would class her as a 3150, maybe a 1350, but that's pushing it.
Not to mention, she gets gold way too fast with her Bounty. If I have to get an item with increased gold, why can't she?
That is merely my opinion and I hope there are others who agree with me.
