So, this happened.
I teamed up with a small group that had us enter Stonewatch Keep. The TL, DR version for those unaware is that it's been taken over by orcs, you need to do some bounties, so get in there and kill stuff. While I was the highest levelled player, the leader clearly knew what he was doing, so we managed to get through okay.
What really sealed the deal is that as we came out, we saw another group of players fighting their way through orcs outside, cutting down the brutes that we'd otherwise have to kill ourselves due to respawning. It was one of those weird, idiosyncratic moments where a moment of gameplay works perfectly as a narrative conciet. We go on, take out the orcs, come back, see the "cavalry" arrive at the last moment to relieve us, having been battered and bloodied. It's something that WOW (and other MMOs, though the only other one I've played to any real extent is LOTRO) has done excellently, because as tedious as the grind can be, it's the serendipity of player interactions that makes it worthwhile (least while I'm using up the month of my subscription).
On a more downer note, I need to get into the watchtower near the keep, but hanging around the area, haven't been able to find anyone high enough or willing enough to help me. What's ironic is that the quest that relies me to get in is marked green (so, easy, right), but no matter your level, it's pretty much impossible to take them by your lonesome - certainly not anything beyond one on one.
Update: Managed to do the watchtower with another player. I've pretty much done all the quests I can in Redridge for now, so I'm back in Darkshire. Events of note include:
-Killing worgen.
-Killing more worgen.
-Dying from worgen.
-Reviving and killing worgen.
-Getting rewarded for killing worgen.
-Trying to kill Eliza, but she's an elite, and no-one wants to help me.
-Get some people to agree to help me kill Eliza, but someone else kills her, and the people who agreed run off.
-Giving up on Eliza, and going to Stalvan Mistmantle. I meet a group outside his manor, we team up, we kill him in 5-10 seconds.
-The group boots me for some reason.
-I go back to Eliza and find someone willing to help me. Eliza is killed, but the quest doesn't count as completed. Either it glitched, or another person who was there got the kill (which I think is more likely).
Yeah, it's a love-hate thing with this game.
