When I'm on my Ranger/Fighter and I see those LFM's and it's excluding Rangers and it's a group I want to join, I'll just send the guy a tell and tell him I know what I'm doing, that I'm twf, decent AC etc.
9 times out of 10 I'll be invited. the 1 in 10 time I don't get the invite is because while I'm busy writing a tell someone else fills the last spot and I get the "srry, full" tell back.
If you do your part to teach folks the learning curve can be accelerated. I'm afraid I don't have a clue how long this learning curve will endure. I'm kinda guessing it'll take longer then before, heck I'm hoping so.
Think about it, we no longer had any misconceptions in the game because we'd been playing forever, and so had everyone else. There was little new blood to NOT know the intricacies of the game. Most bow users had learned when to use the bow and knew when it outright was the worst possible weapon to use.
So now there's new blood. Believe it or not they don't have our range of experience. You know playing for 2-3 months is far less time to accumulate knowledge and experience then playing, oh I don't know, 2-3 years . If someone who's been playing for a couple of weeks has grouped up with some really bad Rangers (heck it could be anything, many new Clerics absolutely hate Barbarians because they've run with some early bad ones who are no AC no defense mana sponges - and at low levels their dps isn't high enough over other melee classes to seem to justify that in a cleric's eyes) that's the impression he'll carry over in his LFMs.
So I for one I hope we continue to have a learning curve, because if everyone is on the same level of experience, that means there's no new people eetering the game, and possibly old people leaving the game, because the game will be dying.
So really, don't sweat it. If you're on your Ranger and you want in; ask. And ask in-game. You'll find it's easier to teach them in the game then on the forums. Most of these "problems" indicate that the game is alive and well. Sure, the new generation doesn't know the joy we had of walking uphill both ways in the snow, but I'm counting on their tax revenue to give me a comfortable retirement . So that makes them okay in my book.
