I know this is an unpopular opinion: SGM and 2E are different games that share the same assets, don't try to make SGM a mobile 2E.
SGM is a fun gothcha game; I like collecting variants and leveling up fighters/moves, collecting and managing resources.
If I wanted DPs, combos setup/ variety, PVP lobbies and less meter dependent game play...I'd play 2E. In fact, I've been playing 2E for years and still do.
