It has been several times already I have been getting into the Crimson Fellwyrm UQ set to Very Hard (Level 70+) and a bunch of players between levels 40-50 clog the instance.
They wind up spending most of their time on the floor since they can't survive the attacks and the few people who actually meet the level range have to work extra hard to actually complete the run.
There needs to be a better way to filter out level ranges for these things so people can actually do these events with out an insane amount of irritation.
