I am going to talk about many points in this post so I apolgize if I am just rambling on or stating what is there, my hope at least is this will conduct a list of what we need at the end.
I just love how everyone is saying KillerKen has Great Smash a tad worse than Reviser for Defense and it has decent stamina, it seems contradicting to me but I don't have one.
I would like to question BH145WD saying D's "Survival Rate" the only reason D was ever used over something like WD is on 230 which it had less sliding and would be more stable I don't know if you are refering to something very old like the Libra 85D combo which I don't know much about. I am thinking Big for BWD here, but if its only a tip then Dragooon can use it too.
Also, about Swaying Combos, it is true that you can sway a Opponent in a opposite Spin Direction but to put it on a exgerated scale you would have to be MSF-H Dragooon Dragooon SA165CF vs Torch Gemios 125WD to sway it.
I would like to state why Dragooon is so powerful and what we need to counter or why we can't counter it, please add on more to anything I might have missed.
Dragooon is a Left Spin Wheel and has weight, in a opposite of whats happening way, its like weak launching a Diablo vs LLD.
Smash Attack: We can't Smash Dragooon Out because of Weak Launching and Weight.
Sway Attack: to effectively counter dragooon we need a Left Spin Close weight Swaying combo, which basically means Use Dragooon to beat Dragooon or wait for a OmniDirectional Zero-G
Stamina: Dragooon can be OS but not on a fundamental scale, we do not want to find simple counters to a combo, like for example, lets say this which isn't true was that, but in the old meta, Burn Beat Earth, but Burn loses to Thermal which loses to earth, Thermal was only used for Burn and was not practical to use. When it comes to spin stealers, its the tip that I find decideds it, you could use EWD to beat B
but then it is chance when fighting the same set up except Dragooon.
Possible Counters: Left Spin Sway, Left Spin Smash, And heres a former concept which theroetically would work but this is Zero-G which can mess it up.
Tornado Stallers
A Staller I guess it would be called in Zero-G would have to not make contact and OS Dragooon how this is possible in a Zero-G Stadium I have no clue, but theoretically A Staller Would work.
