So let's be short:
Gun UV: Clip size
Would give the user more bullets before reloading. Also works on charges. (Yes, I know this will make Vanaduke easier and that the polaris spammers will be boosted, this is the point)
Bomb UV: Explosion Range
Would make the explosion range bigger than normal. For bombs such as graviton or dark reprisal, only the explosion would be affected.
Sword UV: Blade size
Would make the sword bigger and make it's hit range bigger.
All the ideas have the same problem, each gun/bomb/sword is different. What works for one, fails on another.
These things shouldn't be tampered with.
ASI or damage are more gloablly accepted bonuses. thats why they work.
Besides you didnt expalin it much. Are they hard numbers or %-based?
My opinion:
Gun UV: +.5, refine the idea so it's more clear.
Bomb UV: +1, But make it a small jump in radius
Sword UV: -1 Swords are already OP and difficult to judge how far they can hit enemies as is, more so with lag. Do you REALLY want to be fighting someone with a GF that has a huge-er range in lockdown?
"Would give the user more bullets before reloading. Also works on charges."
How would this affect Callahan's charge? Would it suddenly fire two giant bullets with Clip Size: Low, making the charge twice as powerful?
