Various game modes call for various teams to be modded up.
Rogue one in LS TB for example... My rogue 1 squad are all g9/g10 and need the best mods to complete all phases.
Outside of that TB mission I don't use them, and those better mods go elsewhere.
DS TB -- empire/bounty hunters/imperial troopers etc. All in the same boat.
I've got plenty of 7/8/9 speed secondary sets... But only about 2 maybe 3 sets in the teens.
I dunno, was thinking out loud really... I like the game mode, perhaps mod-management QOL will make the point moot anyway.
Cheers for your feedback
