More tips and tricks for the new system after the break.
Other tips we've heard: finding an instance as tank or healer will go even faster than trying to get in one as DPS, so if you can specialize into a more useful role and just want to grind out instances fast, do that. Damage meters are supposedly broken -- they haven't figured out how to track ranged damage across realms quite yet. Which may be a good thing, as lots of players never liked following those meters anyway. The vote kicking system seems to be working well -- the number one reason we've heard that players are kicking each other is that they're going AFK without notice, so if you're in a random PuG queue, be sure to be ready when it pops up to do the instance ASAP. Oh, and let's just agree right here and now: Frozen Orbs are Need, unless you don't want them for some reason.
And maybe the most important tip we've heard: it's important to make sure that your gear matches the instance you're doing. The number one issue so far seems to be players who show up for a Heroic in greens, or people who queue up to tank without having any tanking gear or experience at all. Thanks to the new system, there's lots of groups to run, and everyone will get the gear they need to do what they want. So don't waste players' time now by trying to take on something you can't do and ending the group in wipes or making other players step up for you. Start out low and easy, running regular instances, and then when you think you're ready for something tougher, move on up the ladder to Heroics.
