My question is how the heck did you get that much!
i was a casual below average player(stuck at act 4) before and i really got into the game like 4 months ago, so i got these units by 100%ing old acts and doing like atleast 2 milestones of arena everyday..i also got lucky twice with the "uncollected arena crystal" that got me 225 units..anyway thanks guys I decided that its not worth it, 1 random (might be good or bad 7 star wont carry me anywhere, but with these units i hope to progress smoothly into TB and maybe paragon one day)
Option: use units to progress to paragon
Get to paragon that's where you should use the units
your roster looks really solid! You should invest it in pushing to paragon, and maybe, valiant as well. Just ignore this, the RNG isnt worth the units.
