Curently in wvw if you are power you will take full marauder (or even berserker, using abilities as survival tools instead, such as invulns, dodges, blocks, evades).
If you are condi, you generally take full dire (or viper's in some cases e.g burn DH bomber).
In my opinion gear in wvw should be more than just the standard "marauder if power or vipers or dire if condi...
How do we address this?? I think the best solution is to tone down damage numbers. They are power crept far beyond what wvw was designed for. A berserker can pump out 2 x 30,000 ard dividers in the space of 3 seconds. A daredevil can aoe pound for 20k crits over and over. Soulbeasts do 15-20k rapid fires from 1500 range. And condi bombs have made wvw about pirate shipping. Condi shouldn't be a huge red death circle that if you touch you die... hell, even cleanses are too much.
I think if damage numbers went down it would be good for the game. It would bring both roaming and zerging fights back down to where they are supposed to be.
Roaming currently is throw as much damage out onto your opponent faster than he can and you win. Zerging is red circle of death.... lower damage numbers would (in my huuuumble opinion) make fights more meaningful.
Currently, there is NO time to react. Of you touch red circle you instantly die. If you blink vs your opponent you will get hit with a 15k decapitating strike.
