Probably depends on what you want to do. If you find a guild that is raiding and gearing now, while filling in its roster, then it’s probably worth gearing up with them.
Otherwise, focusing on gearing after reaching max-level for Wrath makes sense, imo.
Personally, I’m planning on rolling fresh, and have a great community lined up. We have been forming over the past couple of months and have 5 raid groups.
