Nah you clearly dont remember that first 2 weeks of this patch before the hot fix. Bubble used to reduce attack speed by 50%, not damage. So ret could pop wings, bubble and 2 shot full s4 gladiators of other classes with quest item, while being invincible. Arcane mage was break fast for ret in that 2 week, everyone was. Then bubble was hot fixed to reduce damage by 50%, then divine storm became physical instead of holy damage. There was never any class outside of a bug that ever got close to how ret was for 2 weeks. I know i had a ret level up just for that because of the beta. Those 2 week i was wearing gear from netherstorm quests and 2 shotting everything in what ever gear they could be during my invincibility. The only way arcane mage could even be in the same league would be making them able to cast spells during iceblock.

To be fair Ret S3/S4 was ok, more successful then moonkin, not really. Moonkin had its use before it was nerfed, Healkin used to be the master of 2s. With warriors, rogue, drain locks. When moonkin form gave mana. DPS moonkin was useless. Ret was literally only good for one thing during TBC 2 final season (useless in s1/s2). Cleave with arm warrior and windfury totem. Anything else ret was useless at. Ret couldnt even duel properly at that time, even seal could be dispelled and you really had limited mana to reapply it mabye 12 times lol, if a priest was in the area well, you stopped being usefull in mabye 3 seconds. The only reason Ret saw plays in 3s, is pretty much a single comp for shit reasons lol.
Ret had freedom to give the warrior.
Ret was the other 2 hander spec gaining the most burst out of windfury totem and bloodlust.
On its own ret was garbage tier. If DK had existed during TBC, the only reason for ret to be in this comp would vanish. The fact that Windfury gave it burst. Hell if arm warriors could have freed another player from root and snare, they would have easily taken ret spot on that team and probably create the most powerful comp of those seasons haha. But since it was a ret, it was just a mid range comp.
