Mega Man 2
This is actually one of the better weapon sets in the franchise. Aqua Cannon should automatically rapid-fire, and Homing Missile should be a bit stronger against regular enemies, but that's about it.
Mega Man 2
- Metal Blade: This is the poster child for overpowered buster replacement. I don't mind it that much, but I'd make a few more enemies immune to it and halve its ammo.
- Bubble Lead: It just doesn't feel very good to use. Increase its damage and give it a small explosion on hit.
- Atomic Fire: Needs a reason to be used outside of bosses. Reduce the energy cost of the charged shot, and maybe increase the ammo overall.
- Flash Stopper: Short of changing this into the Bright Man version, all I'd really do is allow it to be turned off at will.
- Everything else is fine. I personally would buff Quick Boomerang, but a lot of people swear by it.
- Thunder Wool: Make it shoot lightning from the time it's fired instead of just at the top of its arc. That plus maybe lower energy consumption is all it needs to have a good niche; you don't even need to take away the annoying "cloud dies when it touches anything" property. As it stands, you will never use this weapon against anything but Pump Man.
- Rebound Striker: Needs more ammo. It's a nice weapon in theory, but it runs out too fast.
- Triple Blade: Needs less ammo. The best weapon in the game by a landslide.
- Commando Bomb: Do a little more damage on direct hit. This is an incredibly strong weapon if used correctly, but the alternative is really disappointing.
- Solar Blaze/Chill Spike: Allow more than one on screen at a time. Two is probably enough.
- Wheel Cutter: Make it start moving immediately when fired.
- Water Shield is great. No changes.
