From my point of view DDD has trouble approaching because he lacks moves with early/fast hitboxes...
I almost always depend on reads, throwing moves as safe as I can, hoping for the best...
aproaching is a very difficult task, if your opponent has a move that is fast and beats gordo, then you are pretty much screwed(talking about vs good players)...
I can accept the fact he has a huge hurtbox, but with the slow moves (compared with the knock back)... he ends up being just an ok character... Roy has fast moves, and better mobility, along with better knockback... the only thing DDD gets over Roy is the Recovery and maybe range(unsafe), but let's face it, Roy would be hitted less times than DDD in a combo string, and Roy can build up percentage better than DDD...
I'm comparing him to Roy, cause I believe he has things DDD needs to be more "balanced", either more combo potencial, faster moves, better killing options (knockback increase), super armor(on Jet Hammer)... maybe if they put high shield damage on Jet Hammer, or any other grounded move so DDD could force it's opponent to do something and not sit on shield and punish your end lag... or the very rouge option of increasing the damage that is needed to hit gordo back at DDD...
I just need a move that is viable for beating shields, Inhale is ok, but is way too slow, and way too punishable and it has some blind spots...
