Thanks for the info.
How do I get in on people? It seems that every character has more range than Jam. I kinda get in by timing a FB puffball through their attacks, but it's not reliable. Other times I try to IAD, but I get punished for it a lot. I have the most trouble getting in against rushdown characters like Slayer and Sol, because they have good options up close. So, when I'm halfway to Jam's optimal range I'm already in their killzone. At least zoners lose options as Jam gets closer, but Slayer gains options!
I really don't know what to do. I end up blocking a lot until they do something stupid, but I know that won't work against better people, and it doesn't really work against the crappy people I play with (not that I'm any good).
Also, what's the first wall loop I should learn?
