Weapons not used (often)

[gozo1985]

AA Gun
Acid Cannon
Artillery
Bombs
Death Magic
Energy Spears
Frost Magic
Glaive Cannon
Machine Gun
Plasma Fragments
Rock Catapult
Soulstone

All these weapons are used not often. Some of these weapons have a good reason to exist but the way they work is maybe the reason why they used rarely.

I guess there are different reasons why:
- most players dont like to switch their weapons (soulstone, plasma fragments)
- many people dont like the range of the weapon (glaive in early game, bombs)
- many weapons are too specific (creep only weapons)

I would like to see a rework of some weapons to make them more useful i start here with what i think would make them more interesting:

AA Gun (more range, more attackspeed, less damage)
Acid Cannon (less cost, less damage)
Bombs (less range, more damage)
Glaive cannon (spreadshot, less projectile damage)
Plasma Fragments (spreadshot, less projectile damage)
Soulstone (less range, more damage)

what do you think?
