You will always attract more casual players like that, or even solo players, who just follow alongside a tag, or stand inside a keep; on siege, while you fight or even defend something. Even if you ask people nicely, most of the time they refuse to join the squad or voice comms and learn to be a bit more of a part of the community. Any WvW events brings alot more Fairweathers, or being in T1 for so long.If you mean roaming specifically, there are too many cheese builds to avoid these days though, group roaming is much more fun.
