Well, rallying cry was removed because of the exact same reason.. They hunted down tier from past expansions to replicate said ability.. and completely bypass 30% of the bosses health with a single ability.. Seems legit.
So, why should your opinion matter? You quit WoW.. Why you still stalk these forums boggles my mind but everyone is entitled to their opinion. Don't tell me mine doesn't matter because I don't have time to dedicate myself to living behind a computer screen. Quit being a pompus asshole who thinks their achievements in video games make them superior to others. I may not have seen every heroic, but I have downed a few and far in between, including current content. Grow up.
