As for CZ itself, everything that this game originated from, revolved around CZ. DCZ and RLB were recently introduced, and people who joined the game after these zones were released have no idea what they are talking about. (yes I"m looking at you). I've played CZ for majority of my almost 8 years of playing, and there is a reason for that... I've also played DCZ for some time as well, and the zone is a joke. Your "we can't mistakes" is just lol. If you mean you can't town on time before you see 2 rouges coming at you... then no you can't make a mistake. Not only is the zone unbalanced, where rouges are overpowered, but it's filled with noobs who are new to this game. The first month I literally joined the server, I was a solo mage running around and KSing the shit out of people like there is no 2morow... yet surviving on para(once in a while) and more on torment and malice. The zone is a joke as I said... filled with noobs.
CZ on the other hand... well let's just say there is a reason why you're complaining about mage parties and "priests spamming healing melees". You obviously don't have what it takes to be a team player in order to conquer CZ... and that's why you're crying about it. "Priests spam healing melees" is what the game is about, and not about 2 hitting anything that's duffed in DCZ as a rouge.
Step outside your level 59 thinking box, and resurface to where you're suppose to be.
People like you shouldn't even start playing this, as it will only be CZ,... and once you do enter CZ you will most likely rage quit, as you will realize that you don't got what it takes to be good... and it clearly shows even now just by complaining about it that you don't got what it takes.
