I can't block very well because it's on th stupid left stick button.
I don't even know how charging works.
oooh. You my good friend were not ready for GP4. You must have had some rough matches on the way to Brass right?
Don't hesitate to go back to 3 and be confident in easily blazing through that before moving on.
By holding block, dash, or jump, your arms will charge up for a time, become more powerful, and often take on additional properties depending on the arms equipped.
Blocking on L3 does sound awful but I won't sit here and try to convince you to try motion controls at the second to last boss of a hard difficulty ¯\_(ツ

What are your other Arm options besides poppers for him?
Sure you can. Save and exit, set arms, and you'll be right back in it. That's why people were talking about "save scumming" earlier in the thread.
Mind blown
I've become so accustomed to feeling like I needed to pick the set I was going to do for the whole GP that I am going to pretend I never learned this
Just the defaults. The normal gloves and the slapamander. I've only unlocked 2-3 extra arms.
Ah, so you wouldn't have the Dragons to pop on anyway.
I'm not too familiar with any of them sadly, but I think your best bet may be to go double slapamander, keep your distance, charge and smack. Max has huge recovery times on most of his arm choices so just wait for the opening.
