The global reason why some carries don't work in competitive is a simple one: they lack utility.
doom is dependant on heavy farm and his only useful skill, his ultimate cannot compete to the utility other heroes bring.
Lol, Doom lacks utility?
No seriously the reason why Doom isn't doing so well is because he's the epitome of gank hero.
Last I checked the rock/paper/scissors syndrome, I believe gank loses to lane control and group pushing tactics. ((Which is the current Meta game. Give Doom some popular hero compositions to gank and he'll be #1 like he was.))
