Luna is pretty crazy. I did just about 100mil damage a minute, and the crazy part is my atams isn't even maxed. I haven't upgraded its modules yet at all. I also haven't upgraded my reactor, this is completely un-upgraded weapon and reactor. Oh I don't have a trigger module yet either. Oh and I'm using some random Invader accesory set because I haven't farmed up an Enlightened Mage set yet. So basically every single thing you can possibly do wrong with this character except just the descendant modules is wrong, and it still feels like I'm doing a lot. My laser beams were doing 200k a pop and you can machine gun them when you max your music energy bar. Oh you can also aim while in music mode and benefit from weakspot hits which does even more.

I think this character is pretty fun. Hitting notes in order to fill your music energy bar, at which point you go spastic with a laser gun is pretty fun. I think it's more fun than just staying in the air shooting an assault rifle with Serena, and it's more fun than just toggling infinite ammo with Gley. It's also more fun than farting in the room as Freyna. So I think overall the most fun characters for me so far are my wife Viessa because she has low cooldowns and you you're constantly aiming skills and moving fast, and the spastic lightshow Luna. Jumping around the room as Valby is also like third place.

I don't really like the swords, but my complaints match most people's complaints. If you consume ammo, it should do more damage, and then you have weaker attacks that don't consume ammo. But they look cool and are fun to swing so they could be really cool if they just make them slightly better mechanically.
