Might as well chime in with the four weapons I'm currently playing.
BRONZE PAINBRUSH
Fizzy bomb and booyah bomb? Wow! what a unique sub, special combo never seen this pairing before. Ok joking aside this is unapologetically just Machine kit except 10pfs cheaper. Fizzy bomb is a mobility tool to help pain get into position, can combo, and deal insane object damage which helps in rainmaker (One of pain's worst mode IMO) and booyah is a great special to keep you alive for a bit longer. This kit works wonders on Machine and I have a feeling it will work on pain
ANNAKI SPLAT ROLLER
Fizzy bomb once again
almost like it's the best sub in game works well with roller for all the reason I said with pain and also with the bonus of helping roller paint for special. Before I thought that chump would be better for roller that was until storm gotten a change where it can heal you and your team. Which makes it perfect for roller it can not only paint an area for roller to fight, it can deal damage to the enemy team, heal you while fighting, and you still have access to your main weapon.
CLASSIC TRI-SLOSHER
I'm going to need you guys to let me cook for a second. Tri already has fizzy, and while we could give it burst that would be miserable to play against. (I love tri but I love my sanity more) so I decided to give it splat bomb as a sub that while it can't combo it is still lethal and wail as a tool to help tri combo but is also a quick ink tank refill and can help displace longer ranged threat that tri can't reach.
CLEAR DAPPLE DUALIES
Listen Dapples had gotten screwed over with FIVE bad kits in a row if I had the option I would give this weapon a 110p atom bomb. But let keep it realistic here, Burst is a combo and movement tool that can also help the weapon finish off weaken opponents at a distance. Kraken is a great up close special that plays in the position dapples want to play in up close. Is this just a better version of Dapple Dualies Nouveau? Yes, do I care No.
Also done the icon myself in gimp pretty proud of them if I say so myself.
