I actually made a list of changes I would make to an updated PSO for fun. It covers mostly weapons currently, but one of the universal changes I would make is to make weapons that can't combo stronger. In terms of damage, they can't compete with weapons that can combo.
Beyond that, I'd be OK...
I always liked the Rianov 5. I have a thing for piercing weapons, and I find the RIanov 5 to be the best of them due to its power, range, and fast projectiles. I only wish it comboed.
If you have one of these, PM me or hit me up on Discord. My Discord ID is in my sig.
EDIT: No longer interested in this. Sorry to all who contacted me.
