Tbc and vanilla are just broken mechanics oneshoting people randomly. Imagine spending hours on hours to get top notch gear on a class that just gets wrecked in a split second. If there's no room for outplay it ain't a competitive game it's just a fiesta of rng to see who is more stacked. Making sure to stack cooldowns to burst someone down within a certain timeframe after forcing out their defensives through consistent dmg and cc ensures that strategy is involved and therefore skill is actually a factor. Part of the reason why corruptions suck. While fun in pve, in pvp its just a RNG reliant game mechanic. Which is garbo. Cause you aren't actually responsible for the outcome , the outcome just happens and you just happened to proc it first. If there's no room for a reaction then there's no room for counterplay , thus pvp turns into pve - mindless -effortless- underwhelming.
