Hey, I've thrown some 3C's out online and if they hit for a counter, there are some nice possibilities. (tested on Tager, Ragna and Carl). And yes, these work without the CH, but you have to be at such a strict range that I don't think it's worth going for (I also don't think it's worth going for a 3C unless you KNOW it's going to hit).
3C CH, 2B, 6C, jc, j.B, j.623C - 4373
That's good damage for no tension and a relatively easy set up, but because a combo is not a combo if there is a throw in it, you can try this out too:
3C CH, 2B, 6C, jc, J.A*, j.623B - 2131
Can sometime hit j.B here instead of the j.B, but j.A seems to be easier. Try it out. YMMV.
Now, this is a little tricky because you can't be at max range of the 3C. It still works at a very realistic range though.
I hit the 3C online sometimes. It's not really safe, but I can get it to CH on reaction vs a B-Sledge from Tager (this is how I found this out). If you are far from an opponent, so they think they can throw out some slow long range move, it could work there too. I just don't have enough experience to know if these are useful combos or not.
What do you think?
