I know that 95% or more of the people that see this will say "Oh, AD TF isn't viable, he doesn't do any damage" and I say thats based on opinion. Everyone plays him AP, and very few if any play him AD. I know, I know that he does too much damage up front as AP, but what about when your abilities are on cool down, then what? You get screwed over if the enemy isn't dead and they catch up to you, because you can't stun them or do any damage with your basic attack. With AD, you get consistent damage output, and crits only buff your damage output considerably. Just try it, you might find you like it.

Use it like any other ranged ADC, stun, then pound them with damage. If you manage to get the items in time, you'll be doing upwards 200-400 or so with your basic attack (I might've got that wrong, correct me if I am) and a crit may very well do 1k or more if you're lucky. Exchanging some damage for AS may help, because if you get to 2.0 AS with about 200-250 AD, then lets just say faces will melt off. Have fun if you actually consider this.
