One of the other issues I'm having with his passive change is that I feel forced to run a full AD page (or AD + LS quints) to have any early presence in lane. I used to be able to go full ArPen and still do the same damage early (1~2 dmg lower at lvl 1 and got way better after that) and scale better into late game. Any other draven players feel they have been forced to swap from ArPen to AD on him for runes?
I tried triforce a bit but wasn't really impressed, draven simply scales too hard off AD to make the sheen proc really worth it. I've been experimenting with double BT as first two major items, I feel it matches dravens style of play much better than going for crit/as early. He pretty much has to be aggresive in teamfights otherwise he does no damage, unlike typical adc's that are better at poking/kiting, the extra lifesteal makes you quite a bit harder to kill and with W up you have enough AS to juggle 2 axes comfortably. I'd usually follow that up with PD/IE/LW with LW earlier if they have made armour early.
