No Sloshing Machine is a terrible shame, but, like, there's still a chance that it'll get buffed in what I presume will be 2.8.0 (range, shot speed, peripheral shot radius or some combination thereof could all be boosted without it becoming broken or unfair). It's got good sets on both extant variants; just really struggles to apply pressure on its own.
I hope this H-3 is monstrous. Not gonna use it regardless, but I want to be able to join a Ranked Battle, see the Cherry H-3 on the opposing team and feel my blood run cold.
As a very recently-inducted Range Blaster player, I'm really excited for what the Turbo Range Blaster will have to offer. Its two present sets are already great, although the vanilla is overshadowed by the Custom in the majority of maps (probably better for some SZ stages with chokepoints, but that's more or less all). I don't think it'll get Bubbler just because it already has invincibility, so... Burst Bombs/Echolocator? That's very different from the two it has and the Sub can save it in CQC.
