Firstly, exactly how likely do you think it is that a PvE only player has more useable experience than a PvP player. Both sets will have completed the game with 2+ characters, and will have learned all the basics. Most PvE only players will then go on to farm after that using solo and specialist (b/p in tombs, trappers in uw, etc) builds given to them here on gw guru, for hours on end. The PvP player will get to learn the skillbars of most builds, admittedly pvp and copied from here, but trying to get to rank 3 and testing out everything in your frustation and trying a whole variety of your own ideas gives you much greater knowledge of the advantages, disadvantages and effects of combinations of skills than farming the same mobs with the same build continuously, at least that was the case in my experience. The only people that will fall outside this are people who clear out fow, uw and sorrows furnace with balanced builds. The balance of PvE player time between playing farming builds and a 'balanced' build I dont know. But in my estimation it swings fairly high to the farming builds edge and I think thats the feeling of most PvP players. And then again you dont exactly know how much PvE experience this player has had, maybe there should be a time played title converted from the /age command.
Second point, why is everyone getting so uptight about rank only teams. If someone gets pissed off with you and flashes a rank emote at you hes just a retard, retards will be everywhere, and theres no excuse for it. But I can see many players just want to go into some tough missions with players that have a similar level and area of experience as themselves. Rank doesnt mean your better than anybody else, it just means there is a really high chance of a base level of competency and that is why theyre doing it.
Finally, we were all unranked once. What did we do? We went into unranked teams. OK rank isnt supposed to be and wasnt used for PvE, but why aren't people just joining players with a similar outlook as themselves, less chance of running into elitist ranktards like you just mentioned. And considering your arguments you wouldnt even want to join such a team because their PvP experience leaves them at a disadvantage to PvE heavy players. So why is an advert in local chat bothering you so much, there are hundreds of adverts that dont apply to you, ie all the ones advertising for classes that doesnt include yours, unless you happen to be a monk

.
Id always henchie my way through and when I would need human players for mission objectives Id take/join randoms. I just dont like this hate attitude that always seems to be going aroung from unranked to ranked players. I'll probably get a few flames back for this but: it seems like you all want to join these ranked teams because you cant trust all unranked players to do their job in a team, otherwise why would an advert, 1 of many, in local chat hurt yous so much? (This point excludes idiots who flash emotes to put across they are better than everyone else.)
