So I did WGT normal today using group finder; this isn't a story about elitists or noobs though

I got 3 legit under 50s, but no problem, it's normal not vet. People are responsive in chat so all good. It's one dudes first dungeon in ESO ever! Okay, still all good.
We wiped a bit at the inhibitor, and I started getting a little annoyed because nobody rezzing, I ask why and no answer. I finally stop and say I'm not going on until I get an answer about rezzing and I find out one of our DPS didn't know you could rez other players (the other didn't have gems)!!!! We eventually got it, finished the dungeon, took about an hour.
I mean overall, you could take the point of the story that nothing needs to change, because we did in fact complete the dungeon; but it was reliant on having at least one high CP player, who knew all the mechanics inside out and was happy to explain, and new people who all understood english perfectly and were good gamers, just new to ESO.
IMO nobody should be learning you can rez other players for the first time in WGT. For every group like ours that was able to complete, there would be 9 more with just frustration. If people understood that dungeons like fungal 1 were easier than 2 is easier than WGT etc, most people would do them in order of difficulty. This game has a big issue with learning curve, and I feel like most of it is self inflicted. If you made it clear to people what a more natural progression was, most people would do it.
That isn't so say you need to force people to a certain order or anything, but imagine you are brand new, level 15 or whatever, wouldn't you like to know that if you want to try dungeons here are the easiest ones, here are the middle ones and here are hard ones?
Lots of suggestions on how to make it work elsewhere, but seriously, until we do we will get 3 complaint threads a day about low CP noobs or high CP elitists, and its not a good thing for anyone.
