Hey Eternal I’ll try and help you as best i can.
Apparently you say that you’ve hit a wall and your skills are getting worse, can you please elaborate further? What exactly do you feel is getting worse?
As far as hitting a wall, you have to set up a training regime. I know it sounds kind of hard, a regime in a video game? Fuck that!
Take it this way there’s always something you can improve upon, always something you can learn. Especially now since the game is still very new.
If i were you I’d really try and nail the absolute must down to perfection, and by absolute must i mean learn how to combo at least 90% consistently from the overhead. It is absolutely vital, and your game will improve ten fold once you’re able to combo that at will. Also learn how to combo from F+mk which is one of Dudley’s best command normal.
I would suggest reading the One, Two, The End! Dudley Combo Thread it’s a gold mine of useful information combos that you’ll need to learn, from easy to moderate to 1 frame links etc.
After you’re able to combo from Overhead or hit your low target combos, it is then that you can truly start and mess with your opponents in the corner and on wake up. Dudley is a beast because whatever way your opponent blocks there’s a chance for you to combo into a massive amounts of damage and that’s what makes him scary.
Now against Turtle characters, you have to be patient rushing in trying to jumpin’ or use duck excessively will only insure a quick and painful loss, maneuver through the projectiles slowly but surely inching forward with f+mk or standing fierce which stuffs a lot of moves and is one of Dudley’s best normal, once you’re in, it’s time to go all out use your blockstrings i would recommend subscribing to GGM his youtube channel has videos covering option selects and blockstrings which are absolutely devastating and easy to learn.
Get close to your opponent pressure them, hit low, use overhead duck into throw use f+mk, lp, lk an excellent frame trap which works wonders against grapplers. And that’s it you’ve got them.
The timing from EX-MGB into duck upper isn’t hard at all once you see the last hit which launches the opponent into the air you input duck upper it’s pretty easy to do actually. Also i don’t know if you know this but after an EX-MGB you can go into duck straight and ultra from anywhere on the screen, timing is a bit harder to do though.
