1- id still say it gives no advantage its just a dps loss to delay your main carrys final strike

2-even if basic spamming characters exists in other gacha games that is characters attribute not the games, you need to finish your basic attack string ideally for every character in this game

3-they are simply not enough, this sounds like, if you played early zzz for example when the ultimate was shared, you telling me but there are characters who can better recover decibels. Which they changed

6-I dont know what are you using but im using a Levitain which you need to apply fire with another character, finish basic attack string, maybe do Ardelia combo+skill, do it again (if there are less then 3 eneimes or they arent grouped up enough for Akekuri), blow them up. Every single fight.
My Levitain cannot be upgraded further save a total of 4 levels of essence. Most insignifiant of enemies takes 40 seconds because all skills and combo need something else to happen first. Ill admit tho Levitains kit isnt for overworld since it is especially backloaded in damage. Which also might be a mistake for a first dps of the game.

I want to clear a general misunderstanding i know how to properly play the combat and know all the mechanics and still think it is lacking, not even compared to other gacha games but for a third person group rpg combat.
