OMG lol and I thought I was the only one
I've been running a RI build with my ele since the AoE changes and no one will have me in a group except for my guild because they WILL FAIL without an echo/renewal MS. It doesn't matter how much success I've had with my build, that I never need energy, or that I never get exhausted. Apparently I'm not effective enough without being an echo/renwal MS nuker
Same thing with mesmers, you have to be e-surge because that does damage. Doesn't matter that there are other builds out there which do things which help the GROUP take down the enemy faster, like the nasty, nasty condition spreading builds.
Once again necros are in the same boat, SS or MM. Period.
I think the problem lies in the fact that players seem to want to be 1337 asap rather than taking the time to learn what the skills do and the best way to use them. Just look at all the people in town begging for money, they don't want to farm because it takes too long, and all sorts of other excuses.
Sadly I think the crux of the issue is that the general maturity level of the players in GW is ridiulously low (in spite of the average player age). Most players just don't seem to understand that it is a GAME, something you do in your free time because it is fun and (supposedly) relaxing.
Now, when making a team, the things I am wary against is:
1) Players in a rush
2) Players who want a certain team build
3) Players who complain about certain professions
4) Players who use "noob", or too much 1337 speak
5) Players who boast
6) Players who want to know guild standing or rank
7) Players who refuse to take res
8) Players who refuse to talk about skills and general group integration
9) Players who don't respond to a question directed at them
These apply equally to PvP and PvE, and following these rules I (generally) end up in a fun-loving, fairly well co-ordinated and successful team.
