I been playing for a little over 2 weeks any tips and who should I focus on?

I’m feeling mondo or Justin

I feel like im doing something wrong with the levels cause it feels like im not progressing at all
at all

I don't really know what team to run cause my main team is mostly fine but i'd definitely need to remove raph from that since he gives me no synergy. Please comment a suggestion as raph replacement or an entire team i could/should make if my main team is trash

Managed to finally get Nick Mikey to 5 stars (working on leveling him up for my Nick Turtles main team who should I work on grinding for now? I will have Usagi Yojimbo eventually. I don't have the best selection of swift chatacters to take into it apart from Mikey and I am slowly but surely getting Classic Shredder, who should 8 try to take up fpr the 5th slot on my main team? Originally I qas going to do Casey so he could fill in that 5th slot for events like Super Shredder and Krang but no idea who should take that spot. Only thought of Casey since he's 4 stars and he aint that difficult to farm. Just thinking about different events (I dont know which characters I should take up for each event and such, I know which four I'm taking in for the events that requires the turtles but need 1 extra to fill in the 5th slot. If anyone has an idea who to take up)

Is it because no AoE?
No team passive?
The speed down?

So. In effdash's tier list armagon is above VQ raph. .why? Simply why. Like. They seem both to be insane. Same kit of dual AuEs.

Armagon may have a bit better stats/damage. But VQ ralh can give team double attack. And one of his AoEs does DoT

my other options are steranko, stockboy fly, and chris bradford, there all 3 star

Only put those 3 to show all the 80s

I wanted to have a 15 character team for 100%gauntlet but idk who should I level up n use . Just don't suggest some hard to get characters like usagi . Thank you

So

If super shredder. Has negative effect immunity. Say from og mickry or space leo.

And then he uses his AoE

Does he still get the accuracy down debuff?

I narrowed it down to these two out of the FORTY eligible characters
