Long term playing considerations

Even just collecting event girls only your going to get alot of girls, so you eventually have to expand unit capacity, so might as well spend a few.
More event girls means you will need equipment capacity, so same thing might as well make room.
although I ahve not hit the unit maximum capacity or the equipment maximum capacity, you do need to spend a few currrently 220 for gear and 300 for girls.

Whale missions have been mentions, but if you look at rewards, i do with spare stamina and am after the exclusive items, BUT they seem permanent, so no rush, also need blooming mats, but you can consider later if your starting/young account.

Gacha rolls, is really personal choice, i like collecting girls, i consider it part of the game, i do spend money on this game, but certianly not a full whale spender, but for the thread, spend the FG if you see a knight in a event Gacha you would like a chance of rolling, but NEVER roll on the premium gacha. if you want a second chance at a event Gacha, wait for a re-issue, collecting FG while waiting.

personally i never spend FG on stamina or Raid points, Stam might be worth while at laters levels, but certianly NEVER with a low level account.
Raid points might be for a event, but have not had to do so yet.

Lastly the discussion about event girls vs gacha girls, my view is event girls are better, not worrying about stats, but it does come down to gear, gear does become really important, even event items are huge increase, so yea, if you think you get a Gacha girl with 4 equipment slots, then they are more powerful than a event girl, but if your not spending cash, and not a fortune teller, then getting that gacha girl with 4 slots is not going to happen happen, you will get duplicates, but your not going to know which dupes, so i would not plan around something you have NO control over.
IF you manage to get knights with more equipments slot, you can always just level them up, knowing you will need the old knight for whale missions, remember whale missions need 40 knight.

Number wise you do not need to get 4 slots on a gatcha girl to be better then an event girl, 2 is enough to out pace the stats of a 4 equip event girl. As for the rest, we already know that gatcha girls are better in both skills and passives. Still free content is free content and I must admit to liking a lot of the event girls by looks and personality.
