I've yet to have any issues with it. Not to say there are no issues at all, but I don't think the issues are the entry level requirements.

It seems most groups that fail are more down to player not knowing game mechanics or dungeon mechanics rather than level.

I think the undaunted pledges is good the way it is. By level 45 (I think?) you should have some basic knowledge of how to run the particualr dungeons. Key word: "Should". It's not always the case and some people will need some instruction. What I do feel absolutely needs to changed about the group finder is the way it groups different levels of people together. Yes, everyone is boosted and scaled to 160, but the problem is when you have a level 10 and 12 running with you. Example: Girlfriend (cp 350) and I (CP 275) were running dungeons the other day. She is a healer, I was a tank. She focuses on pure healing and I focus on pure stopping power of incoming damage. Both our DPS are not necessarily the best. We got into a dungeon (can't remember which one it was) and we were grouped with two level 13's. At that level, even with scaling, their dps was minimal at best. We were pretty much running the dungeon ourselves and when the two of us rely on dps to take things out it made this dungeon unbelievably painful and slow. Took us almost 45 minutes to reach the final boss and we didn't even finish it because we could not put out enough damage.

Then there also lies the problem of the lower level folks who join a group full of CP toons and refuses to do anything and be carried. I am not running dungeons to carry people through. Everyone needs to pull their own weight. I really feel that groupd finder needs to have toons organized into groups of levels. Say every 10 levels. So like all level 10's through 15's in one, (the exception) then level 16 to 25, 26 to 35, 36 to 45, 46 to CP 10 (example) then everyone else after that.
