I am from this server as well. I PvP quite a bit. I find that it is usually one or two people who screw things for the others most of the time. In nc we have 2 guarding and they don't notice the stealth that snuck in behind them and capped the node with them standing right there. I have seen this happen a lot. Also pubs only seem to call for help after they have died. There are exceptions but that send about standard practice for pubs.
I think this goes for both sides, if you can't break 300k damage in a full length void star, please go read up on your class.
I'm not the best pvper who can carry a team, but I know my role and I do it better than most. I've done some ranked. I've done plenty of regs. Things sway both ways. Just keep your chin up. Play to have fun. Even if we don't win, I don't get upset like I used to. Just go with it and maybe you will get a better team next time.
Also, that guy who had the ball that you and 6 others were wailing on was probably tank specd with 2 healers behind him. Got to have people n those healers too!
I was in some awesome matches the other day. Before the match started I asked the group to attack whoever has ascertain symbol over them. I was marking my target that symbol and we burned through the people so fast. It was nice to see that cooperation.
Keep your chins up pubs. Keep trying to improve on an individual basis. Analyze what you could have done different. And adjust. Don't get prissy if someone offers a suggestion.
