I've already leveled and forma'd a Nova. Nova wasn't troublesome to level, mostly because I was going to keep it, and it had a Reactor in it, so it got stronger as I leveled up because I could more mods on it.
This Loki, like my previous Mag, Ember, and Frost, lack a Reactor, so I couldn't install any decent mods on it. And like this Loki, I didn't put a Reactor in them because I wasn't keeping them, 'cause I was going trade up for their Prime versions (except for Mag Prime, which I already had at the time). It's mainly for the mastery EXP, and for the codex because having the Primes with stars and the regulars without bothered the hell out of me.
EDIT: Found this on the wiki.
