This thread seems usually quiet, let me fix that.
Much like in the first game, the L-3D is still an amazing Bust Cancel weapon. One indirect hit from a Bust Bomb and a full burst from the L-3 is a guaranteed splat making it more potent in close ranged combat then the original.
The Inkjet special would had been an amazing addition before the initial Inkjet nerfs that gutted the special but now in it's current state (after the projectile speed buff and the slight buff to making the hitbox size a bit smaller) it's a decant special but I find it more difficult to execute and have a big impact compared to most other specials in the game due to it's high aim requirement and you can easily get shut downed by curtain weapons (like Blasters, long ranged Shooters, or Chargers).
Overall, I love it as much as I love the vanilla L-3 but I do find the Inkjet a bit diffiuclt to get used too.
