just gonna drop a couple of quotes i quickly found to justify my answer.
you were talking about wotlk in this post… there was no room for theory crafting if you ever did anything at a high level, there was always a ‘best’ spec.
from the same post - thinking outside the box in many situations means you have screwed yourself out of mandatory talents. there will ALWAYS be a best spec for pve encounters.
and based on your achievements (300 arena wins before 1550 in any bracket) you are awful at pvp too. but hey man grats on 100,000 HK’s and not learning anything.
and one last point - you talking about bfa pvp
just to make you aware - you are the last person who should be straying from meta builds based on your ‘success’ to date in pvp.
