I love the fact that they have made it possible for solo players to do dungeons now. I am not in a guild as I prefer to play solo. I have played wow since its launch and still love it.
However, not all people want to be in a guild or look for a group so. I find most PUGs are aggressive and want the run done at ridiculous speeds. if you don’t keep up or your gear is lower then their standards you get kicked.
So it would be great if they could make it so we loners could do the dungeons on Mythic and Heroic as well. Also maybe throw in a raid for us soloists too.
