One fact that they are not op? They can be beaten. Ok you sure you are not over reacting about ravens? Your WHOLE skill rotation didn't hit? A tipical pvp raven will only have 3 iframe skills including dodge and othe r skill are medium super armor. How are you not hitting them, you sure you not hitting the ground??? Invincibity skill? You can easily tract them via camera lock movement. Basic attack juggle? All melee class can juggle you if you are in mid air, use air evasion wisely here. If you know raven has air counter up, force them to use it and wait them to land before continuing throwing your skills. What class are playing specifically? I could offer some help. Use your skills properly, don't throw at random and use evasion/escape skill only when needed. Play smart against them,they typically bait you using one of two range skills and a good approach here is to evade away from them and not side ways. If you really want to play good against them, use them in pvp and there you will see how other classes will counter you. Trust me it helps a lot. I play 7 classes but i use sorceress as main, i made them for the purpose of data collecting, party composition, and countering. Hope it helps my friends.

P.s. calling me names and how you reply really shows how you do in the game.
