This should go for everybody, If you lack units to get through the begining or the basic content, you will want to summon until you have a decent squad.

If you're mid to late game and just need much stronger units to deal with trials, raids, special vortex events, then you will want to save your gems until the best possible time to summon such as rates up on newer units, 3 gem summons and summon 5 get 1 free(With rates up on newer units).

That's for F2P though, if you pay then spend your money vigorously~
