There's really no point in it outside of achievement hunting. LTS will get your railgun requirements pretty fast. You might be able to get them in Frontier Defense; I'm gen 10 though, it's been a while since I've had to do shyt for regen.I've regenerated like 4 times already.
It's fun and you level up quicker every time you regen.
I hate the railgun though, never been a fan of that shyt. I'm just doing it to fulfill my requirements![]()
