Why are you not using your first account?
On big stages, it's not very good, so maybe it COULD use a small buff. Maybe just the length of the super.
No, as that would potentially get more kills on smaller stages. I'd agree to making it faster, however.
In bigger stages, you need to make sure they're positioned correctly. Like, in the middle of the stage. That's your best bet for at least 3, probably 4.
Fresh to death
That would be a hard thing to do. Stages like Columbia and whatnot seem like G.Cole should be getting 4-5 easy, but as you said Black Rock and Franenza are absolutely torturous. I don't think they can mess with it without just giving him a entirely new super though. Speeding it up would way overpower it on the smaller stages (Time Station) and it's already a impossible to dodge vortex.
They should buff Heihachi's level 3 as well, he should launch 2 rockets, the second one would have background characters depending on the stage, in Metropolis he would launch the Hydra, all three heads strapped to one side, for the Hades stage it would be Hades himself strapped to a rocket, and if the stage has no background characters then he straps himself onto a rocket, this should get him 4 to 200 points worth of kills.
you..I like you.
I have yet to use Cole in a ranked FFA, but i did enjoy playing him in arcade and all that. Might actually try him out more online once thigns get patched up. I WILL say, the reason for his low amount of guarenteed kills is due to other than holding the analog stick towards the opponents, there isnt much you have to do.. Just make sure you corner the side with the most people when you first send it out.
As a cole main myself, i think his level 3 is fine as is.
just bait them into to the middle of the map, which sholdn't be too hard since cole is an annoying character like radec.
then boom, 3 automatic kils,, then move the tornado close to one corner of the map. Not completely on the corner but close.
as soon as they respawn, that another 4-5kills right there
