You've summed up nicely everything I was going to say about this post (but you put it in way better words than I could have. "... dreadfully inexperienced and socially retarded..." I giggled.) So disappointing to see the reaction to this post on a designated RP server, where you'd think it'd be most welcomed.

Wish I could help, but I've also been doing the same. Skimming that thread you put up from the PTS, someone said around the Ulgo palace. He later went on to say that the crystal formation had a two hour cooldown on the spawn. Yikes... Wellp, back to searching! I'll letcha know if I find anything.

I have also been having some problems on my Sentinel, and am glad I stumbled upon this thread. I've seen others in PvP just slaughtering, so I assumed it was just me not knowing how the class worked. (And it was! No surprise there.) Hopefully, I'll be able to integrate some of the helpful tips and tricks here into my playstyle to help me along. (Most of my problems were the same as the OP's. I felt too squishy to justify the damage output, like I was just running in and faceplanting. I use T7, but hadn't thought of letting the little guy run in first!) It looks like almost all of my problems have been covered by the previous posters. I just have one question to add. My sentinel is currently 33. A lot of people here are saying go Watchman, but I recently spec'd into Focus, (the additional leap, ignoring 20% of opponents armor, and a few other things looked like fun) but now I'm wondering if I'm wasting my time with it. Should I go back to Watchman? Is the difference in playstyle with these two so dramatic that it'll change my entire gaming experience with my Sentinel?
