Hello.
I'd like to talk about high level people (or people who with low level characters but good gamesense, champion points and equipment) who frequent Random Normal dungeons. I think they cause trouble, because they make an already easy experience too easy. What I mean is that:
1. They often deal a lot more damage than their low-level counterparts, so many enemies are dead before the newbies have a chance to learn and experience all their attacks
2. They know they can rush in and survive without problems, so they do, which makes the tank's job harder. I know, this rarely ends badly, but I believe that the purpose of Normal Dungeons is to teach players the mechanics and roles, and rushing players prevent that.
3. Foes die so quickly, many healers have hardly anything to do, so they either get bored of healing, or stick around long enough to be overwhelmed by Veteran.
I've been trying to learn tanking for a while. I have to get aggro on enemies and control them, either by taunting or immobilizing, but it's damn hard when every other person I get paired with charges first without waiting for the tank, and many of them are high level players
So, how do we do that? By making Random Veteran interesting. Right now, you have a choice to either do an easy dungeon for a reward, or do the same dungeon with quadrupled difficulty for the exact same reward. There's absolutely no incentive to try Random Veteran, and so they choose Random Normal. Maybe if Random Veteran had 50% higher rewards, or if players who reached level 50 were getting reduced XP from Random Normal, or if you had an Undaunted quest to do a Random Veteran once a day, or if pledges only counted on Veteran dungeons... something should be done to make Random Veteran rewarding and meaningful, which would also help new players, by reducing the amount of overpowered and/or hasty players they might be paired with.
