Now here's an issue people are gonna bring up... getting carried. I've encountered quite a few incompetent (or illiterate or slow or mentally fragile) players while running CM (easy carry), WP (moderate carry), and AK (difficult to carry if tank/healer). I usually run in a group of 2-3 with my FC friends and we have carried the random undergeared character through these dungeons... but it gets progressively more difficult.

With 2.1, they are planning the MVP system and the Duty Purpose system which will allow you to select what you are running the dungeon for and match you with people of like mind (hopefully not too many undergeared selecting Speed Runs, although skill can make up for gear in some instances but gear can NEVER truly make up for a lack of skill).
