Lately I've been playing a lot of tf and my only problem is with his e. The attack speed doesn't suit his playstyle at all and he is ap so no need for that. Very frustrating when I port bot and forgot to get my e and lack a decent amount of burst. I think riot should keep the same concept but instead of every 4 attacks make it so you have to activate and your next auto deals the bonus damage. I'd like to hear your ideas on what they could change his e into and maybe riot will hear us.
I have a friend who plays jungle tf a bit and the attack speed on hit component is a big part of his non mage, off builds so I don't think they should change it
Besides, there's another skill set for tf players, managing his e passive and gold card for the most optimal gank, making it an active aa buff takes some of the skill out of playing tf
It's weird but tf is a weird mage, I wouldn't change it
At the same time, if you're comfortable with doing so, 
isnt a terrible item on him and does make his E a good deal more useful.
I have experimented with nashors tooth build and it's ok with the passive cdr ap an as but it delays my build a lot and each game I want to get lich luden zhonyas and rabadons for a ton of ap damage but nashors is sacrificing some ap for consistent damage which is not the best on tf.
Remember when AD TF was a thing? They still mention it in his spot light.
I don't really like the activator idea, as it would make any kind of AD or AP/AS build harder to pull of. But at the same time, The activator itself would cause problems, should it proc Lich bane. (an item just about any AP TF would want.)
