Current state of blue vs. green?

[Fammaden]

People do PuG all the time on green, but there are a ton of inexperienced people in those PuG's who might drive you crazy. So much laziness, tabbed out autoattacking, afk manasong camp bards....even at the higher levels. If you're used to the hyper efficiency mindset from years of playing here, it gets pretty frustrating at times when only one or two people in a group are pulling their weight.

Part of the problem is on blue the conventional wisdom is that full groups are a waste of time, duo/trio is the min/max approach to XP, and many alts have the gear to make those small configurations really cook. On green generally the PuG's just fill the group, even if its suboptimal or not a needed class. Two tanks? No problem, you're in.

Overall the population disparity and the prevalence of actual new players on green makes blue a more challenging place to LFG for XP.
