Aigis is grindy as its finest at first 2 months, then you slowly start enjoying real gameplay, while still grind&level your team a bit but i sense you'll get tired (not bored, obviously) easily from this type of grind considering the things you write here. Pvp games have that type of no-grind just play type of gameplay, other than that dont expect to take on a G maps with full silver-gold half-cced team. Anyway good luck with that.

Btw, how come you claiming you've been playing for "years" (lol) and your max levelled unit is at 30lv?
