I have almost all the skins in the game for the brawlers i have(missing crow and spike). I never buy megaboxes w/ gems; i always go for skins cause i aint no sweat. Just got rockabilly mortis today too
Honestly I’d say if you have all brawlers start maxing out your account and use gems on token doublers. I have 7.5k trophies with 5 star powers when most people I know ranging from literally 0-14k trophies have less star power than me. And we’re ALL free players btw.
