First off, welcome to PW AnnaLove.
I agree alot with what you said but I don't think Sheamus is that stagnant. His development is slow but I think it's happening. I agree that ADR has gone several steps in the wrong direction and they need to get him back on track. Sandow is definitely a future star and with the push it seems Rybak is getting, he'll probably be there as well.
As for the gimmicks, I'm sure I fully understand what you mean. I got the impression you were alluding to every wrestler having a "character" like in the late eighties/early nineties when the E was filled with plumbers, mounties, repomen, prison guards etc. I'm sorry if I misunderstood you but if that is what you meant than I have to disagree. I hated that time in wrestling because it was too much like a live action cartoon in my opinion. I just thought it was too unrealistic. I get that wrestling in general is unrealistic but that time and those characters seemed too over the top. I'm fine with having a couple characters like that from time to time but only a few at a time.
