I've read all the comments in the previous threads and I've yet to find anything regarding Draven, not one peep.
Last Draven had a buff was one that turned out to be a noob trap (reaching 6 consecutive minion kills without dropping axes) but the cd on it was too low and it turned into a major disadvantage in actuality.
Then you changed it from 6 to 12 sec and didn't announce it anywhere.
I wrote a pretty extensive topic regarding it, and the challenges Draven face, in this new game, as the obstacles he has to overcome are now far greater, such as zhonya (Bard), untargetable+'stun' (Tahm), walls (Yasuo/Braum) which are just some that can screw up juggling his Q.
Not to mention the current meta of bruisers/heavy champions running rampant in bottom lane during the laning phase, at a point where you're just getting to have some full items.
Which means that the point of the game where you're supposed to snowball as Draven now turns against you.
Then there are all the new mobility champions and obstacles he have to overcome, overall too many champions and options are now available to make Draven's life very troublesome, have you thought of any changes that would highlight his role as a 'high dps snowball adc' ?
Personally I would have a look at his E, and W, if you tamper with the mechanics of his Q a lot of people are going to be extremely sad.
Adding a QoL to his ult would be cool, to show how far it will travel after being activated a 2nd time.
Or what about having 2 stacks of Q if you activate your ult.
I'm just throwing it out there, but what is the plans for Draven?
