eh? everybody is entitle to their own opinions. You're allowed to find characters boring. If people get offended by it, well stiff biscuits. It's not like you're parading around the forums complaining about them every time their name pops up.
But at least there's variety. When I personally think of boring juggle characters, I think of all heavyweights, somewhat Lisa, and a few others. Mostly the characters with little variation after a launch =P Lisa revolves around 3 main strings in the air, Leon goes for the throw, Bayman knocks 'em straight down in 2 hits, etc. xD
Codemaster, you main Pai right? so juggle variation isn't something that bothers you then ;O she's kinda lacking in juggle variety. Tbh, not many characters have a billion options... Kasumi is the only one that springs to mind that does.
Hayabusa's actually got what I consider to be a decent amount. Not a ton, mind you, but enough that you're constantly switching between them to optimize your situation. Most people end everything in an air throw for raw "void damage" output, but that's either because they don't want to risk his other options, or don't know how useful they can be.
I would never say Ein is boring, he's still practically a DOA2 character sure but he isn't boring the only thing that gets old is having to do PP6PK so much after a juggle because it's the only REAL way to get damage.
if anyone I find boring it's Mila(all takedowns), Eliot and Alpha-152(KKKKKKKKK = Win lol)
Grapplers on average actually feel very fluid to me, with the stiffer ones being the exceptions (Leon/Bass). But Lisa, Tina, Bayman, etc. actually all feel quite fluid, moreso than many strikers (such as Kasumi, whom I find quite stiff).
