I played spriest shs rogue in 2s, and rogue was still way easier in TBC than it is now.
I assure you, RWD pre harpnerf was just as faceroll as any catacleave (didnt play wotlk so can't comment).
I had 1 PvE item and it was the badge trinket (berserker's call), the rest was full PvP, so yeah...
Clone is just way too strong, it needs to be fixed somehow.
I only played it before the nerf, and I got glad safe in those weeks, and please, Stormherald wasn't outdated in season3...
I won't argue that Harp wasn't faceroll, but as someone else already mentioned, it was extremely short lived, so using that as your basis for argument is way off base.
99% of the season Harp was a non factor, so I fail to understand how it's relevant to the argument.
Even during the Harp shenanigans though, it still wasn't quite as potent as current melee cleaves (yes it may have been equally easy/simple to play, but not nearly as strong as things like S6/S9 TSG, Beast Cleave, Frost DK/Rogue/Healer, etc).
