One of the things that's hardest to get across in terms of the Warlords of Draenor beta is how many small improvements are being made at the same time that gameplay is being trimmed and shaped. UI elements like the map, quest tracking, the toy box, an extra void storage tab, seamless scenario triggering - it all kind of runs together and you don't even realize how much change is wrapped up in this expansion. New character models, new gearing systems, new statistics, it can be a bit much to take in.
Are you feeling overwhelmed? Keeping up fine? Trying to figure out your spec, your class, or what the garrison will end up feeling like?
