You do not need an invite to zone in and watch, only to queue.
Guild is located in the large building in the Valley of Honor.
- The design of the system is that you slowly work on fights. Your first queue each day skips you to the front of the line. After that expect to wait anywhere from 30-120 minutes depending on the crowd. The area is cross realm. Some people complain about that, but I think it is a required to make ''content'' out of it. Blizzard created a nice spectator sporting event.
The design of the encounters also favors dps specs. Again, some people complain about this, but it is the best way to tune things exactly how you want them. The alternative would have been a balancing mess, creating either frustration or watered down content.
- Specs and reforging are two things you should be prepared for. Up to the second half of rank 6, all of the bosses are lvl 92 elites, so you need slightly less hit rating. Melee can also take parry into consideration since they'll spend alot of time in front of mobs. Plan on changing your talents and glyphs on every fight (I've gone through about 100 tomes of the clear mind).
- Buffs such as flasks, food, kings, might, etc can all be used. It is like dueling someone outside of org. Currently you can also be grouped with a mage and have them bloodlust just before you're ported in for your fight. I've seen alot of well geared people not be able to get a fight down without that trick. The tuning @ the end is pretty tight. There is a vendor on the north side of the arena that sells cheap potions specific to this area. No flasks are sold here.
-Queueing is done by talking to any guard located around the arena. Talking to them again will give you a rough estimate of where you are in the queue. Remember that people who haven't done any fights yet that day will ''budge you in line'' causing your queue to take much longer than what is actually listed.
-Score boards for each rank bracket are accessed by talking to Skizz in the southern nook. They are considered the boss's record, and as such are listed as their wins vs losses. (30-90 means they've killed 30 players, and players have killed them 90 times.)
-The Haters Gonna Hate achievement is one that you should plan ahead of time and then when it is almost your turn ask your fellow spectators to spam throw fruit at you. I suggest planning it because with the number of people in there so far, it isn't possible on multiple fights because of the high level of movement. I chose Mazraheen at the end of rank 3 because you don't have to move. People can begin spam throwing the fruit as soon as you get in, you just need to keep the debuff from falling off, even the 5 seconds after the boss dies before you're ported out.
