Anet announced ages ago how they would always let WvW players know beforehand (alteast an hour) that there was a new build before we got thrown out.
Now all thats changed is you say there will be a build available in the next hour but what you really mean is the next 3 minutes.
How hard is it to just care about your WvW player base a bit and let us know an hour beforehand and actually have the build upgrade an hour later?
