It's possible, and overall I don't exactly play DDO 24/7 plus I have a few lower level characters that I'm playing with as well.
Sorry, I meant the Vale explorer area and quests, my bad! Also, I rarely have the trouble of not getting accepted, but I often get kicked because they find some flaw with my character after one run. Granted the Vale parties don't usually do this to me, but it's happened before and overall my point is that it's uncomfortable to be playing with these people.
Low to Mid level, public groups are so nice. High level, people are a lot less friendly, a lot more zerging and worst of all judging. I know I have to make an effort to not suck, and I do, but that starts to not be enough, and leaders start to get alot more comfortable with kicking people on the smallest flaws.
Haven't played with my wizzy in a while, but this was my experience of Thelanis 2-3 months ago, and I was very disappointed. I really wanted to see more of the Macabre, Devil battlefields and Reaver's Refuge amongst other stuff, but did not get any chance.
Again, though, this is just a concern related to this topic. While DDO is getting dumbed down and that no doubt sucks, there are also some problems like these that persist and I felt like mentioning it.
