The PTR is different than Beta. It is testing of new content, and I guess also evaluating class changes. I have really never tried it. I have once or twice logged into it to see how a major class change would feel to me. But I do not have the knowledge or skill to evaluate whether something is great, or broken. I wouldn’t know the first thing about trying dungeons at high difficulty or raids for that matter. To be honest, I don’t think that my opinion would matter at all.
I always took it to be the time when the worlds first folks were in there working on strategy to be ready on the major patch day to hit the races. But I wonder if there are to many of the more elite type player, and not enough average folks in there. Mostly I don’t know what to look for, or what they want tested. Sure they can change values of stats, can make adjustments to tier bonuses, but what if you don’t have the top gear, what if you are not a great player.
Do they even want me in there?
