Remote controlled rockets that can fly at ~120 when boosted and deal quite a bit of dmg but make you unable to control yourself when controlling them, so once you die the rocket explodes. Or we could have those tiny-tiny versions of robo-legionairres that have them tiny-tiny chainguns which shoot tiny-tiny bullets. And the lil bastards have limited lifetime and a self-detonate function. They are faster than normal legionairres but can be shot down quite easily. Chaser weapon of my choice
Water cannon (deployable or just equipped). Sorta hitscan. Very low DMG but a constant impact, no explosion (duh). Shortish range, yes but the cannon won't be good enough to bump a 120 m/s going Raider under 90 m/s. It'd be interesting though, especially for flag carriers waiting on a tower for their homeflag to be returned.
Mag Disc. A boomeranging magnetic disc (I've mentioned that in the IA forums). After you shoot it you can activate the magnet in it and make it follow you at an increasing speed (hence increasing the damage it deals). You can also deactivate the magnet in case you want to send it off, then activate it. The disc has hp and can crash or be shot down, but its quite flat so its hard to hit with a rocket or a grenade, easier with a CG on short distance. I don't know how will it balance though...
A melee weapon. Most likely a
tazer that deactivates the enemy jets for ~4 seconds. It takes a while to charge after it has been used and it needs to be used EXACTLY when in contact with the enemy. Don't think that giving it to all of the classes is a good idea though. It's just logical for the legionairres to have SOMETHING melee. Too often I come in direct contact with the enemy.
Glue gun. For ground uses mostly. The presence of a flag within ~50m of the glue melts it down and renders it useless (so it isn't OP in CTF ;p). A legionairre that lands on the glue needs a certain 'breakthrough' amount of energy to rise up in the air. A legionairre that travels through it experiences increased friction. A legionairre stuck with a high enough amount of glue temporarily experiences the same effect as the one of landing on the glue. To make the process of sticking the glue to a legionairre hard the glue is manually dropped in a container by the player and either needs to be remotely detonated or shot down for the glue to be distributed. Flows down the hills (slowly).
Airstrike gun/ The Dropper (if we want to be cool). Now the names don't sound right so I'll need to come up with something better. This gun
drops (like vertically, straight below the legionairre) unfuelled rockets (aka bombs) in series of 3 on whatever is down below the legionairre. The rockets travel at the same speed as the legionairre when he drops them, although OFC the air friction slows them down. A chaser gun + defence disturbance gun. If you consider the base sizes/shapes it doesn't seem OP at all. Now I quite like this one, because Outriders will finally have a weapon with which they manage better than other classes thanks to them being able to fly high up etc.
A grenade launcher variation that simply shoots smaller projectiles that travel faster (longer range) and cause less damage/impact, but can be shot quite quickly. Think of a shooting pace thats 50% of
this shooting pace and of a similar projectile parabola (ofc in Legions scale). Reload every 8 shots or so of constant shooting.
A variation of the above grenade launcher (the main idea behind the GL variation, only it's easier to portray after describing the above) that explodes automatically in air once it reaches the top of it's projectile parabola (once they start heading down). Shoots slower. Think of it as of a
Flak Cannon.
Now none of the above are substitutes for the primary damage dealing weapons. I think of all of these as secondaries or even tertiaries/equipment. I know some of these ideas were probably suggested before (I think someone mentioned airstrike-like concept on the IA forums), but I wanted to dump all of my ideas somewhere regardless of inspirations.
Yes, I know that if the devs decide to get any of these weapons into the game, Mabel will have so much work to do that he'll just find me, chop me into pieces and make a Propkid soup.
