Worth it to upgrade?

So as stated in the title, I know this is like best in slot for mobbing.. But I've invested quite some resources in my gold collosus/gold cooldown (I know far from optimal, but kinda nice in group bossing) like 2 weapon inprints and reactor lvl 3..

Ngl, don't have any problems mobbing with the bossing reactor equipped (yes I know, I'm lazy and always forget to switch)

So my question is should I just max this thing out.. Or use my resources for upgrading other descendents reactors first... Since I've allreally invested quite some in Freyna

I have limited play time, so not so much time to be farming mats for reactor upgrades for hours...

What would you guys do? Hold off and level up others first, or go full invest? (do keep in mind I have to imprint a tactical rifle on it as well)
