PVE vs PVP Player Base

I recently re-rolled on a PVE server to play with a different set of friends.  I'm actually more frustrated with the dungeon finder than ever.  I'm playing a warrior this time about and i realize i have a better understanding of most classes than first time players.  The dungeon group finder however makes it overly easy for unskilled players to get carried through content.


I understand that there is no surefire way to prevent unskilled players from using the dungeon finder.  When leveling on the pvp servers the dungeon finder will only pull from other pvp servers and I've had fewer unskilled players in my groups running the same dungeons.  On the pve server I seemed to be plagued w/ tanks that can't hold aggro or block or mystics that don't know what motes do or what a healing fairy is or priests that have no clue how to manage mana.  I'm already forced to queue as dps as a warrior now i'm forced to deal with unskilled players.  


I've had the to finish a dungeon 3 man w/out a healer or lancer because the tank got mad i took aggro when he failed to hold it off the priest and the priest had queued with the tank.  Now I realize that warriors can queue as tanks to protect us from terrible tanks but if you're going to be "protecting us" how do you propose you save us from terrible lancers/healers?  The only things that can stop you from using the dungeon group finder are item level and character level.  I'm hoping once the warrior/lancer patch goes in warriors will be able to queue as tanks since getting a new healer is relatively easy however finding another lancer is impossible if they fail to perform.


There are only two reasons i can think of why the pve player base seems relatively unskilled compared to the pvp.  One is there are just more people on the pve servers because they like a more casual game play.  The other is they are never actually tested while they are leveling.where on a pvp server you have to be prepared for ganking of sorts and you do test your skills against other players which makes it easier to gauge you game play.
