Well.. the way I think about it is that there's nothing stopping you at all from making a small, intimate group.

The best example? There's one especially famous close-knit group that is very famous, but very small. The limit cap doesn't matter if you want to be small.. since you don't necessarily have to conform to what everyone else does. And, the small, exclusive groups can be just as yearned for and popular as the big, casual guilds.
On the other hand, however, if you
do want to have a big happy casual community (like the GWOnline guild), it's hard to have only 50 members because you slam your head on the member limit pretty early on.
Of course, the main reason that I'm ecstatic over this change is purely out of blatant self-interest.

A higher limit means that I might be able to add a second account to my guild without being eaten up by guilt in taking up a valuable member spot.. and I bet that also goes for some who have more than two accounts, also.
One more thing though.. although I love instancing in this game since it eliminates all chances of ksing/camping.. sometimes it gets rather lonely. A big happily chattering guild in the background solves that for me personally. Even if I don't participate and/or stare blankly at my surroundings oblivious to any and all text, all that friendly bantering filling up my screen makes me feel like I'm still a part of a community. But of course, that's just me personally.
