I don't necessarily agree with this, a lot of level 40 warriors can own face, and a lot of mages absolutely cannot get ABS at 40, much less easily. But the real issue is you're talking to a newbie and using acronyms.

RBW means Rager (battlerager) Berserker Warrior.
ABS means Aura/Barrier/Shield, which are dam reduction spells.

I do wholeheartedly agree that you, guy who deleted, are not spending enough time with a character to understand how it works and how to be successful. Not sure it's 200 hours, but certainly not 20something. Despite what some say, the game does not start at hero. Try to take time at every level or every couple levels and play around with the skills/spells/supps/abilities you are learning, beyond just while leveling. You need to use them in some pks (which you'll probably lose) to see how they work in practice, what they can do, how they lag you, how effective they are, etc.
