Shadow Form in the Victorian times
Firstly there will always be something to complain about. Nerf – Buff – Change you will never please everyone all the time.
One of the changes to Shadow Priests in 3.3 was making Vampiric Embrace a buff.
Vampiric Embrace: This talent now provides a 30-minute buff that cannot be dispelled, instead of a target debuff and only generates healing for single-target shadow damage spells.
I now had a justification to set up Power aura’s for my priest. I could set it for inner fire, and now the Vampiric Embrace buff. To make sure I had it on me all the time.
Remember in Bg’s in the good old days before they had the mana-free buff period. I would lose half my mana before stepping out of the graveyard – sure I can fit in the more mana expensive ones when rebuffing after a death in a bg, however,
Now It takes 6 buffs with global cooldowns to get out of that graveyard.
Fort, Spirit, Shadow Protection, Shadow Form, Inner fire, and now Vampiric embrace. This seems like an excessive lot of time to get dressed after dying.
Of course I don’t need to wear all those buffs I am sure I could neglect a few layers of ‘clothing’ but the buffs are what give us that little extra survivability – they make up our identity as a spec and a class.
Mages have the issue somewhat – but what other class and spec has 6 buffs to put on before doing anything?

now, my spriest is an alt and I mostly pve on her so I can see how it might bother you more, but as a pveer – I love the change. this means I have one less thing to worry about in my rotation
