I invite you to test the classes you complain about so much, play Archer, Ranger for 2 weeks at node-war and open world fight to see the perspective from the other side. If you want to reduce their dmg, take off some of your gear to see the difference. Is that what you want? let's turn some classes into something that no one plays anymore? Get your gear based on the class played to get the perks of each class. It is normal for some classes to beat other classes more easily. How Musa/Lahn/Witch succc beats the archer in many ways. For example, with Witch Succ, you hit him with many mobility debuffs, thus becoming a very slow class and you can easily beat him because the gear is built to benefit dmg, not protection. 

Again, you complain about something you don't know

I invite you to play archer for 4 hours or even more and let's go test this. I can come with whatever class you want. It's very funny that you talk about a class that you don't play and you only judge it because you lost on your class for lack of experience. I lost very many times against ninja/kuno. I think the problem is with you.
