Beta is massively disappointing to me for a few reasons Gared and if I were you, I'd feel pretty good about not being in it yet.
#1 Monk is nowhere near ready for the big time. Missing entire talents, most of it's current abilities way out of whack (the very first AoE tanking ability it gets doesn't even create threat) and alot of animations are either missing or jerky. Monk is at least 5 updates away from being a real class.
#2 Panderan is maybe 60% ready. No voiced characters at all. Not a single Panderan npc in the game has a voice at the moment. There are missing animations, jerky animations and clipping animations. You can't even fully create/customize them yet. No racial mounts etc etc.
#3 The 1-10 Pandean island isn't complete. Some of the biggest cut scenes aren't implemented and all you get is "filler text" telling you what is supposed to be happening. Alot of the ambient sounds are missing and the good music is maybe 2 songs tops.
#4 500k people on 4 servers. I don't have to tell you the nightmare that's like at the moment.
#5 Even with all those people on 4 servers, there's next to none in the 18-80 level gap. So if you had plans on playing a monk from 1-85 and seeing how it grows, not only is the class not finished, you're going to be doing it solo.
-- I have no coment on the island of Panderia itself as I'm leaving ALL of that to be "fresh" for me when the xpac comes out, but I can imagine it's not fully ready either. So really
Gared, you're missing more of a headache than fun at this point. A few builds from now though? When it's almost ready for release? That's when the Beta will be interesting to play.
