Like others have said, it's totally reasonable to have your limitations when looking at Jedi RP. Most of the Jedi are dead, and when live comes around I don't expect to see many Jedi at all in Eisley like you see in the TC. Right now, most of the people you see on the TC playing Jedi are folks trying to get their builds set up, whether or not they're running "Roleplayer" tags.
One thing to consider when you see Jedi RP, however, is how your own situations might seem to other people in the world. There's been times when I've seen people in -crazy- situations in SWG; blaster bolts everywhere, emoting of dozens of stormtroopers that aren't actually there, and surely their characters aren't going to die in that situation. They'll find a way out. Is that a bad thing? I don't think so. You're going to encounter some outlandish RP in every MMO you run into as long as it's an MMO where people RP in the open, and Jedi RP isn't really that different.
It's your prerogative to not take Jedi RPers seriously, but there will be some who are great roleplayers and it would be a shame to discount them just because Jedi are canonically endangered. A few years into live, after most of the meh Jedi were inched out of the scene, you were hard-pressed to find someone actively carrying a lightsaber on their belt, let alone their person. I think we'll see the same thing here.
I totally agree btw, the Jedi being one of the main classes is actually a serious issue. I don't think anyone really likes it from a lore perspective, but most people don't consider themselves "bad" Jedi RPers. If you encounter one, you might even be doing them a favor if you tried to politely explain something they're doing wrong. Back when I first played a Jedi in live and was completely noob to Star Wars, let alone RP, I had no idea that I was doing wrong by open-carrying a lightsaber. Seriously didn't get it. I probably would have responded a lot better to someone telling me rather than just being blocked by a lot of people.
