Which 4* demi-god tier to rank up?
Im a beginner player rating 45k, currently my main team (for story and event quests) are 4* Rogue 4/40, 4* Voodoo 4/40, 4* MS 3/30; and 3* 4/40 Blade, 3* 4/40 Stark Spidey (3 stars are all sig>30). But im considering ranking up a 4* to 3/30 to replace my StarkSpidey. As a beginner the only resources im missing are ISO and catalysts. So which one to upgrade first changes a lot.
Another choice is upgrading some more 3* to prolong the infinity win streak in arena (in other words u think that my 3* StarkSpidey is better than all these following 4* to 3/30). Which one should i rank up first? Thank u.
