Alright lets address these in the order you presented them.
Quote:
1) Can I create an arena team with let's say 4 people and only do mostly 2v2 ?
Yes, each arena team can have up to 10 players on its roster. So your 2v2, 3v3, 5v5 can each have 10 different players. You can choose any of the 9 on your team to run 2s. Hope that made sense.
2) Do you get absolutely no points if you don't win a match?
No, you get points regardless as long as you play 30% of your teams games. Obviously you points go down as your score does, but I dont know think its possible to get 0 points. Maybe but very difficult and tedious.
3) I was thinking about keeping my tank gear on except for my sword&board and use my 2-hander for arena...is this viable? Since my tank gear is fairly respectable atm but my dps gear is kinda shabby.
Tank gear can work in BG's fairly well given the situation, but Arena is a whole different animal. You may last a little longer but your dps will be so pathetic the other team wil just toy with you. The only class your tank gear would really give you an advantage would be rogues, druids. =( Run BG's for your Vindicators gear. Dont worry about doing amazing in Arena at first. There is a learning curve that takes time and also adapting to your partners playstyle and vice versa. Get used to using all your tools, ie: disarm, Spell reflect (macro time), TC, and Demo shout are often overlooked in Arena but can really make a difference. Sorry got off track, but I hope you get the idea.
4) Is doing 10 matches a week hard to accomplish, is there long queue times etc...
No it is easy and can usually be done in an hour or two. The ques for me seem to be longer, the night of the arena reset, becuase everyone is trying to squeeze in some games.
