Aye, it will be the same for everyone.

Though you should be able to get a 50% if you do your things right at least and minor climbage in rating, until you're decently geared out you will surely have problems nonetheless. I bet ya if Aelli would equip blues or starting level 70 gear, he'd go down as well. Because you're simply too overpowered (by others) in gear at that point. xP

I expect a tough start, but I'm setting on farming some gear asap, + the level 70 honor reward faction blue pvp set will help out a lot. Just try to get 8k hp and 100 resiliance minimal before starting though.. (Well, by all means start for farming some points, but I don't think having less hp/resiliance will get you anywhere but down. xP )

You can always beat better geared teams if you just do the things right and they don't, but ultimatly you won't have the power to down a good team if they're doing their things right too though. And you have to expect other teams not to make mistakes in arena.
