You said Enhancement had more than 3 talents, than immediately list the 3 in enhance with the other 2 being in elemental (elemental Warding) and the armor from heal coming from restoration…not enhancement talents.
I know what tanking was like on enhancement. I tanked in WotLk using defense gems.
The talent tree never supported tanking the way feral did for bears. To claim it did is a blatant lie.
We had means to tank, but it was no supported much past lvl 55 and after that required specific hodgpodging of gear and creative use of mechanics/stats (ie. Defense gems to reach crit reduction cap).
Anticipation, Shield specialization, and Toughness (the actual “tank” talents in enh) are not nearly the same amount of talents feral had for bear tanking. Additionally, best for did more than increase armor and also gave attack power and health. They were also taken over paladin and shaman because they had a set of fire resistance leather that had actual stats on it of epic quality, making them decent for both MC and BWL.
