I agree. For me, it's all about variety though, and while I'm all for the inclusion of smaller, more athletically gifted guys, I typically prefer the bigger and/or more charismatic, larger-than-life characters since they're generally far more entertaining. Give me the Brock Lesnar's, the Dean Ambrose's, the Bray Wyatt's, the Roman Reigns', the Ryback's, etc. over the others all day long. Not that smaller wrestlers can't have charisma (Eddie Guerrero and Daniel Bryan) or carry the ambience of being an ass-kicker (Chris Benoit), but more often than not, it just jives better with size. Imagine the Undertaker or Stone Cold's gimmick in the body of a Daniel Bryan.
On the flip side, I consider myself a fan of guys like Seth Rollins, but I wouldn't want everyone in the company to start fitting this mold. I still want WWE to put more focus on larger-than-life personas and not just start looking like your standard Indy promotion. It's why the most interesting prospect in NXT for me currently is Kevin Owens since he doesn't look cookie-cutter and feels more like a legitimate ass-kicker.
