At incarnate levels, Ageless is what really plugs that gap very well. My badger is DB/WP and when I'm not being stupid, it tears thru stuff. That said, I do have to pause to continue that chain. At least solo. On teams with support, no issues. (which applied to everything really)
Scrappers I've kept even after my string of culls:
Katana
Ninjitsu
Been really enjoying this one after it was parked for a long time. Fairly solid and versatile
Claws
EA
Mostly unstoppable and claws is a fun set
Energy
EA
Energy hits like a truck on single targets and does enough AOE
MA
Ninjitsu
Another fun combo
Broadsword
Shield
Classic Combo and does pretty well.
Psychic
Regen
Not the toughest grouping, but zero end issues. 😄 Just watch out for speed and regen debuffs. Back off as needed
Claws
WP
the EA version works a bit better IMO, but easy to play
DB
WP
Ageless saves it, but like I said, it's my badger and has gone thru all the content
Battle Ax
SR
Battle Ax is just a fun set that pairs well with most
Street Justice
Bio
Current a placeholder, but went from 1-50 in a day of marathon TFs.
