His FTilt still has godly range, he's got an ok projectile game, he's got a great recovery. his Utilt is a quick killing move, his smashes can kill at low percents.
No. No DDD does not need help.
DDD's F-tilt is blockable on reaction, he can't actually projectile camp against anyone who doesn't take dumb commitments, his recovery is alright but SUPER punishable, and his U-tilt is SUPER telegraphed and very difficult to land on conservative players, and his Smashes are for the most part not viable moves. Without his chaingrab, he no longer is able to do reliable massive damage to compensate for his extreme lack of any reliable KO moves.
Yes, he probably needs help. I personally think he's worse off than most characters in this game. The best grab can only do so much if all your throws can do is tack on bits of damage. He has trouble actually utilizing most of his movepool effectively on stage since he can't actually approach with his crap mobility and huge stature. I mean, he's obviously not bottom tier since he doesn't get autogimped and he can shieldgrab like a homo. But that's basically all that's going for him.
Changes I want to see to Marth:
+1 to throws. both a buff and a nerf, this should remove a few chaingrabs that Marth has on certain characters like Falco. Possibility of losing F-throw to F-smash exists, but Marth should also appreciate a slight knockback increase on his Up-throw for emergency KOs
-3 to all versions of the last hit of Dancing Blade. Tell me why this move doesn't deserve it. <_<
Change I want to see on G&W:
-1 to first four hits of B-air, +1 to last hit. The theory I have behind this is to unpolarize certain matchups he does really well in, and to help his harder matchups. The reduced damage means that people who are constantly pressured to death by this attack should survive longer. On the flipside, the reduced damage means it is harder to SDI, which makes it harder for say Marth to SDI and punish it, and the final hit getting a damage buff would go some way to help get Marth offstage.
Change I want to see on Snake:
-4 to D-throw, +1 to all other throws.Mostly a nerf, but this should encourage more variety to Snake's grab game.
Change I want to see on Falco:
D-tilt knockback increased. This is mostly a useless move due to Falco having better, safer options, but seeing that Falco lacks solid KO options, he should get another viable option.
That's all I can think of off the top of my head for balancing characters.
