Yeah DK does have good things going for him, but his weaknesses far outweigh his strengths IMO; especially since there are higher tier characters who do the things he is good at much better than him.
- Slowish
- ****ty shield
- Only a few usable moves
- Terribly predictable approach
- HUGE target, eat's hits for breakfast (note this also contributes to his shield problem)
- No reliable way to get grabs in for his desperately needed CG game.
I mean the list goes on. That being said, I still love the monkey and he is currently my favorite character to use, but I hate this current wave of fanboyism that has been poured onto him since BUM's performance at MLG.
DK does not belong in low tier. He is fast enough that i wouldn't call him a slow character. And he has a lot of useable moves if you know how to use them. He has more KO moves than just about anybody else in the game (b air, u air, f air, giant punch, b throw, d smash, and up b). He can combo the top tier characters. Yes, they do have the advantage, but that's pretty much what skill with DK is, is having the ability to get that grab. There are a ton of ways to get grabs, you just gotta know when to use which method. His approach isn't that bad. His b air is one of the highest priority aeriel moves in the game and it's easy to spam it in the faces of characters that are tall/slower in the air. As for the shield, just light shield...duh. lol. Oh yeah, and you don't need to chain grab fox/falco to win..it helps, but isn't necessary. If you watch most of my matches/pkmvodka's matches/bum's matches, rarely do any of us really chaingrab. We combo a lot, and it's rarely a 0-death.
I have an idea that might help you out...practice playing fox/falco without trying to grab them. Instead, try to knock them to the floor. Most of your grabs on falco are going to be from tech chasing of some kind, but that starts with knocking him to the ground. It works on fox too, not as well, but works nonetheless. Don't try to grab falco the normal ways, practice knocking him to the floor and then tech chasing. This is also a great opportunity to make use of the dash attack. If when you tech chase, they keep spot dodging you or shining you when you go for the grab, use the dash attack. If they spot dodge, they'll get hit with the dash attack since it's out there forever. If they shine, it'll clank with your dash attack, leaving shield stun on the shine, giving you a free opportunity for a shield grab. If they're under a platform, and they get hit by the dash attack, they'll land on the platform, setting you up for a free u air that can start your combo, or you can just jump up to the platform as close to the edge as possible, and throw out your giant punch for the length of the platform...it's not escapable if done right
