I suppose they have better kits than they do now? That doesn't mean much of anything considering their vanilla counterparts.
First off H-3 D. Well yes it is nice to see it get Cherry's kit from Splat1 as it was a fan-favorite of sorts. Would've preferred to get suction instead akin to it's Splat2 H-3 D kit. The wall feels a bit redundant when your special is also a wall. Maybe over a year from now when H-3 gets it's third variant kit we'll see it get suction again.
Rapid Pro Deco is interesting though. Marker can allow for pretty quick kills when you get directs with the main. Granted that's easier said than done but the fact it's a possibility for the weapon is pretty cool. And wail is nice for dislodging stubborn opponents which is handy for a weapon like this. It's still pretty awful at dealing with any aggressive weapons but that has always been its Achilles heel. Hopefully Line Marker can get a substantial buff this upcoming patch otherwise it'll probably get ignored along with the other Marker weapons.
As a side tangent. We still haven't seen any new weapons with Tenta Missiles or Crab Tank since launch. We might never see a new missile weapon ever again, but tank ought to return at some point.
