I think what you’re overlooking is, arms is in a state where it doesn’t counter anything.
And being the only class that can still be kited (hurray for rets and dks with 30 yard ranges, and WWs and DHs with actual unlimited mobility), with low damage, just feels really bad.
Now post Tuesday it is noticeably better, but there’s still no classes in the game we actually counter so your argument is falling pretty flat.
