Still in wrath you got mana back from crit heals.
In wrath holy pala got divine plea.
Good luck trying to get mana with auto attacks in a pug raid where everyone ulis running around eating the fire on the ground.
Like I said, other than fights like HM Thorim, I was always in melee range hitting the boss and getting loads of mana back from Seal/Judgement of Wisdom. Also the guild I was in was pretty competent so people were not just running around like headless chickens eating fire on the ground, I didn’t do pug raids because why would I when I had a guild to do it with? Most bosses were kept in a single spot and were only moved if a specific mechanic required it. It’s up to you if you didn’t want to be in melee, but there was a pretty clear added benefit to being in melee vs being at range.
