Does Draven Need a Buff?

Lets all take a look at everyone's favorite champion, Draaaaaaaaaaven. Now I love this champion. As an ADC main I love to throw out the Draven in games where I deem fit, and then get the enemies to "ff at 20" because they're getting 2 shotted by the Draven. In games matched against lower leveled summoners, this champion is a true monster, and is used to stylishly massacre your enemies before they realize you aren't throwing axes, but freight trains filled with his enemies tears. Now, you get into evenly matched games, where very few deaths occur, and a siege quickly turns Draven into a out of mana, easy to detonate target. Sure, you still do tons of damage, but not a whole lot more than a Caitlyn who heavily out ranges a Draven.

What does this mean? When I play Draven, I find myself having to build Essence Reaver, just to sustain my mana long enough to do anything at all during a fight. Sure, I can practice preservation of my mana by not using my axes to farm, or not spamming Blood Rush (W) to try to get a few hits off, but this still does little. Draven is completely reliant on his Axes, his passive and high damage output depends on having one or two up during every fight. The fact that his kit drains so much mana makes him near useless by the time a fight comes around. Unless I'm coming to a fight from the spawn pool with a full mana bar, I find myself unable to even ult in most fight situations.

So buff him? I think a small rework to his kit is necessary. Either an increase mana pool/mana regen, or slightly lower mana costs on abilities. Because so many champions are viable (even Urgot somehow), I think Draven needs to be at least considered for a slight tweak, in order for this champion to bring a tad more to the table.

Agree? Disagree? I'm open to all suggestions. Leave your comments and tell me what you think!
