In lvl 16, its impossible to kill a maxed gear warrior in 1 v 1... It might be the gear that is OP because there was no pvp during the l16 cap and warriors need a lot of armor to withstand the elite mobs. There are no more elite mobs so you can buff warrior armor :0,
In 1 v 1 u can spam everything against warrior and the ELITE WARRIOR (max gear, decent build, noobs warriors are a bit of a challenge, EVEN NEW WARRIORS ARE A CHALLENGE) will still be alive and they will heal back to full with VB heal also. Because u have spammed ur skills u have no mana. So ur dead. Even if u dont spam ur skills u will eventually run out and the warrior will have endless mana thanks to VB.
- NERF warrior armor, warrior gear has OP stats,
OR
-NERF warriors VB, warriors get unlimited mana almost... Of course if this happens lower mana consumption of warrior skills.
OR
-Reduce Rogue's mana consumption, way too high atm.
OR
-Nerf warriors 2 sec invicibility.

Take note, i am talking about l16 PVP froma rogue.
I saw similar things in l21 pvp.

ELITE ROGUES DAMAGE RATIO IS LOWER THEN ELITE WARRIORS HEAL RATIO- rogues do some damage, not higher then the amount that the warriors can almost instantly heal back.

I may have missed some points.
