Guild Wars 2

This is a small idea:
engineers gain “weapons slots” in which unlocked weapon kits are stored/locked. These would be underneath the current weapon slots, and you can’t move them around or salvage them.

In these slots would be your weapon kits. You can add sigils to them this way (remove sigils by using a salvage kit, not destroying the weapon kit but calculating the chance of recovering upgrades and like that return the sigil or destroy it.).

The next bit is an additional idea. I am afraid that I do not now how weapon kit damage is calculated currently, so keep that in mind.

Now, take the flamethrower. A new lvl 1 engineer would have a ‘rusty flamethrower’. At lvl 5 it replaces itself with ‘dented flamethrower’, the rusty flamethrower disappearing altogether. The ‘dented FT’ and has slightly higher damage (displayed as weapon damage in the weapon slots). At lvl 80 you have a strong flamethrower. Perhaps engineers could do an additional story quest to get a legendary flamethrower?

Or, by double clicking on the weapon kit its ‘type’ could be chosen. (the current barbaric/warriors/givers/carrion types)
