tbh i think milim would have done more damage with a diffrent buff than the crit buff in the Gazel fight, i did the fight afterwards with my own 1st anni milim at lv 92 with Space Violet and the EX Izis debuff (120 Secret skill res lower) and did almost 600k (590k ) as in your case the gazel still had 100 crit resistance so she might have actually done more damage without the crit
This Guy protector is underrated. I used him for normal battle Jubilee 2 and his lords ambition prevents you from getting hurt by poison so I was able to get max points without bringing 4* Gobta to avoid poison. This protector will be good for Jubilee for scenarios such as those
I said you dont bring Gobta since lords ambition takes care of the poison from damaging you. Milim is the DPS for Guy protector so of course you bring her when dealing with light enemies
I mean... with powercreep the fact that his dmg support is trash might not matter as much, but I'm not convinced he's pushing Velzard off the jubilee throne
