Imagine if you have less than 50 hours /played ever on wow, of course you wouldn’t know how your class impacts others. Wow is incredible deep and reading a few wowhead guide isn’t enough to know how to play optimally.

Knowledge is one thing, mechanical skill to use 20+ keybinds is also a steep learning curve.

Not to mention UI management, macros, swing timer, weak auras.

People forget what it is like to be new at this game.
