please balance your game
Agree, the difficulty (if you can call it that) in this game comes from the BS stuff that NPC’s can do
This is an MMO, welcome to games where NPC’s are capable of doing things you are not.
Yes, you either ride the storm out or kite. If you aren’t keeping a ranged weapon on every class for that purpose you are failing to utilize everything the class has to offer. You complaining because you don’t have a skill to counter them is showing your lack of skills. Kite something that moves faster than you do and is unsnarable (yes it is possible and have done so repeatedly on multiple classess) shift your expectations into buffing you and instead make use of everything your class has to offer. Yes, this means you will be using weapons you aren’t built to utilize to the fullest to take down an enemy or two.
Using a specific skill to counter an ability is not skill, it is lazy mechanics that limits the build you can use. If frenzy had a specific counter to it, then to kill those creatures you would be required to use that skill, no matter what your play style you would have to have that skill as the game is balanced with that in mind. Instead the game is balanced to force you to be flexable, less on skill selection and more about using varied weapons (melee/range , dps/tank , dps/support).
There is no difficulty in games where you must use a specific skill to counter something. This game uses flexability and the fact we can dodge. If you still find enemies unkillable, shift your build away from glass cannon styles.
