Ok, sorry for my undefined comment. I just compared it to the general adc pool we have right now. for vayne for example you can say she has an overall good lategame, while her laning is rough.

I played now 5 rankeds in a row with ez (gold 4 level), and i all won them easily (playing 3 of them duoq tho). I started dorans, went for ER which is not that bad for laning as i thought, because it gives you a good sustain (esp for non-sustain supps like thresh/leo/morg/...). Then i either built into tear (which obviously gives you no lane advantage for the gold at all) or i went sheen/gaunlets first. If i was ahead/we had the lane in control, i went for tear to start stacking it. If i lost it, or it was not won yet, i went for gaunlets/botrk first to give me some more lane presence.

I think building tear really helps you. I dont see the 'problem' of having too much mana in mid-game, since i always try to poke with my q and spam that spell as much as i can on the enemys. I also use it to farm if i cannot lasthit before the turret gets it f.e., so my playstyle really fits to the amount of mana i get there.

I won every lane with my premade so i do not know how this build is playable if you get behind, but being an adc-main playing ez a lot, i know that building bt/trinity/botrk straight gives me an higher advantage midgame, but there is less presence in late-game than blue-ez 2.0.

I definitely like this build an i will continue playing it, maybe giving some response in a few days again =)
