Better mystic for aol path 2 and 4

Aleor

I currently consider r3 longshot and r2 sym supreme. I can r3 sym, but not sure if he would be better. Looks like longshot should be able to do all those fights, I'm only not sure if he will work for cmm. I also have doom r3, but after doing one path with him I believe I'd rather have symb, who had higher damage as a 5* and got me solos on vtd and aegon easily. If there are any specific fights, where doom shines, please say what those are
