You usually get one for free from Hell's Arena. They show up relatively early. They're used for breaking walls, and occasionally the corpses near the walls, and occasionally the Arena Master.
You do the Wall right, you dump the Rocket Launcher. You get your master trait, half the time you dump the Rocket Launcher. Even its assemblies, useful as they are, feel the sting of not under-use, but under-utilization.
Why? Because they don't behave how rocket launchers should when in the hands of a trained marine.
Here's a list of possible tweaks! Not all of them necessarily have to go in, or are necessarily good ideas, or will necessarily not irreparably break the game, but they're things to think about.
- If an enemy or black space is targeted, it behaves as normal.
- If a (visible) floor is targeted, roll to hit the tile in the crosshairs.
Failure hits an adjacent square. Super-failure can perhaps take it further than adjacent.
Maybe give it rocket-jumping stats, since it's not a direct hit: half damage, maybe lots of knockback.
- Lower base accuracy.
Someone without a keen eye can hardly be expected to hit the right square with such a heavy weapon.
- Halve damage dealt to self from splash all the time, like from rocket jumping.
Allows better use in melee, but not nearly as good as mFA.
- Reduce damage dealt to (certain?) items on the ground. Flesh melts more easily than steel.
The reason rocket launchers are never primary weapons is partly because of this.
- Revenant's Launcher: becomes essentially an s-modded Rocket Launcher with big dice and a tiny blast radius.
Alternatively, make it a weaker exotic with an added low drop rate from (non-rezzed) Revenants? That'd be sorta cool.
- Missile Launcher: almost always hits a targeted monster, but can't lock-on to walls or floors.
Possibly explodes if it travels too far (misses), at least clipping the target with the blast?
- Start brainstorming master traits that do well with rocketeer builds. Fireangel for the melee rocketeer! Pyromaniac, whose distance damage drop-off is improved! Rocket Whore, who can carry 3x the rockets! Or cram 3x the rockets into their launchers, or shoot three rockets for each trigger pull, or reload their launchers in a third of the time, or make them never miss or whatever. Or the dreaded mMB: Master trait Michael Bay, whose rockets get BFG-like splash (and whose BFG splashes are all absolutely ludicrous).
I was thinking about how useful rocket jumping is, and how silly it is that you can't utilize the same basic idea, except not aiming directly at your feet.
I was also thinking about Hell and its seventeen million rockets (and Revenant's Launchers), all of which will get left behind by my marines with bottomless plasma rifles.
I was also thinking about how awesome rocket launchers are, for serious you guys, they're explosions you shoot like from a gun.
