The game is starting to get frustrating to play.

* You've added a pvp event where there's a great imbalance between classes. 

* The game does not fit the word role-playing-game anymore, the roles of other classes other than berserker and corsair are trashed by the system. How can we say if it is a role-playing-game if there are only 2 classes every where we go?

* You can barely see any diversity of classes in game.

Class Balance Suggestions

* You should have a strategy that counts how many seconds of i-frame and super armor does a specific class can use within a specific amount of time. This should be distributed to classes according to the damage output it can deal within a period of time (higher damage and higher mobility classes should have lower super armor and lower grab immunity).

* Add a skill that cancels out any another skill that is currently casting (like Grandmaster's Shoulder Thrust). This type of skill should be applied to every class.

* Buff/Heal skill diversity Berserker with its already high skill damage he still gets +100 AP from vengeful wrath meanwhile other classes only gets +50 AP. Let every class enjoy a total of an additional 100 CP but distribute it through AP and DP. (Example: Titan/Destroyer gets 20AP 80DP, Grandmaster 50AP 50DP, Sura 120AP -20 DP) or something like that. 

Game Suggestion

* You should add a farming party system where players share the same EXP and loot (drop rate would be calculated as the avarage drop rate within the party) include additional drop rate percentage according to the number of party member, this will greatly help new adventurers and increase the bond between players. Lower the "damage to monsters" bloodkin buff and greatly increase it when your bloodkin is within the same area of the map as you are.

* Add bit more wider UI for skill buttons might as well as separate the game UI size and Skill button size.   

its too hard for them to grant your suggestion bro, because they dont have any brain..
