Great description! You put a much finer point on ideas I kind of had a "feel" for but couldn't pin down objectively. You described my splooshing to a t. Swim speed + ninja. Rushdown or stealth flank. Moving along the walls, etc. The mobility is a key point to me.
That explains my difficulties with dapple. (well other than that I suck at dodge roll :p ), It does sound like the dapple plays more like a shooter, where sploosh plays more like a brush/roller, and considering brushes and rollers are my other mains, and I've never really mained the shooters, (other than sploosh) I'd feel a little disjointed with it. And if they aren't really a "better sploosh" at playing like a sploosh, I might as well stick with sploosh and use the vanilla duelies when I want to go "shooter meta" (though dapples can be fun too.) (I know enperry is the most popular duelie, but burst cancelling is just too tempting for an old eliter/carbon main :p )
I think, for me, the dapples present a conundrum to my splooshing. I used to sploosh with beacons and harass with wail. Now the dapples got my beacons, so that play style I had with sploosh is split uncomfortably between sploosh and dapple (and nobody uses beacons in solo, sadly.) Curling bombs are great for sploosh, but I find I don't use them as much as I could since it makes my path predicatable. I haven't looked at the mined spoilers, but I'm hoping the Neo will have tentamissiles.....that replaces wail as the "stop for 2 seconds and fire and forget a harassement special, then capitalize on the chaos from behind" special. Not sure what I want in a sub. Splat bombs would be amazing. Suction would be kind of useless (why zone away if you want to get close?) , burst would be interesting. But it'll probably be point sensors like the old neo which was always kind of so so to me.
Flingza....I don't know...the set doesn't seem half bad. Well, more to the point, it's half bad. :p The wall just seems so silly on it. And on these new maps in general. But if I had bombs would I waste the ink on them rather than on the roller? Not sure I would. But that special is so powerful given how fast the weapon charges it. I'm not sure another kit would really be better or not. The vert hitbox, no question needs a fix. But I don't know, wish it had another sub, but not sure I'd want to get rid of the special. Unless it gets baller. I'd be all over that. :p But if I use the main roller to kill it becomes a carbon with an inking ability on the vert. The real trouble is when I accidentally do vert while fighting, or try to roll over someone the horizontal only tapped because I'm afraid I'll accidentally vert if I flick again :p that keeps happening.
Just remember, if it gets a buff and becomes laggy dynamo godly in a later meta, remember I was the hipster that defended flingza and tuber before it they were cool.
