first I want to say that this has turned into a nice thread with lots of good pointers and tips so thanks to all who have contributed.
I roll a VIG DPS Guardian (ATM 0/28/5) and the combination of a aging computer that can't give me good frame rates during war zones and a lack of skill in MMO PVP in general were making the enjoyment factor all but null. Despite this I kept trying, hoping to get better and knowing eventually I'd have a better computer. So I figured I'd hit the forums for tips and found this thread, while reading it I kept seeing people say "TANK TANK TANK!" and think "But, I'm DPS.." and others pointed this out too and I thought "yeah what about the 2 DPS trees?!" and these posts had really good advice that I will later put to use, but since my DPS wasn't going well do to the above stated reasons, I figured I'd give this tank advice a shot.. after all, I have the stance and abilities that just collect dust from lack of use.. The results are I had a lot of fun! I'm not a good tank mind you but what I do is find the healer on my team and frakking guard the hell out of them! Funny thing is I still get as many kills as I was getting trying to DPS and I'm getting points in defense/protection so my scores are higher. I'm also getting medals and even managed to get a MVP vote from I assume an appreciative healer Now, I'm not going to re-roll as tank because I still prefer DPS in PVE but I can faux tank enough in a WZ to at least not be complete dead weight to my team until I can get a computer that isn't on it's last leg. I'm not saying everyone should give up on DPS cause I've seen many of the videos out there of Guardians doing mass damage on the battlefield but I just wanted to share my results in case anyone else was struggling with skill and PC woes.
