As it happens in other games, isn't it nice to have the "suggested" flag on some server when you create a new character and need to choose your world? (or "low", "high", "new", "rp" tags, whatever)

Suggestions doesn't "force" no one go there, people still can choose, and SE's ones are just hints.

When I play the game for my very first time, and I see there is a selection of worlds, I'll explore that and to me all worlds are equal, unless I see those tags, that may help me decide where to go.

It may be extended to datacenters as well, especially if the players isn't "exactly" in the supported regions. Choosing datacenter, the client may "ping" them and flag to you the ones that seems to be the best choices (other than the text telling you which region they cover).
