Sometimes it's obvious when your team sucks.. but really, who cares - everyone's trying their best (mostly).
The ONLY thing that really gets me down in Warzones is when people give up prematurely.. I hate it when 3 people are camping a node on Alderaan (sitting down etc) for instance, when it's obvious the fightings going down elsewhere, just to get the defender points or maybe they're just lazy...
I prefer to go down fighting at least!
Looking forward to hitting 50 (am 48 at moment) - PvP has become my favourite thing in the game.. which is ironic, as before starting SWTOR the thought of fighting other players constantly made me cringe big time. Go figure.
I also used to suck.. but now find I'm nearly always top damage/kills/objective points and either 1st, 2nd or 3rd on the table. Whoever said Vigilance Guardians suck at PvP needs their head examined.. they rock IMO.
Learning new things is rad, etc.
