I Main Shadow priest and dabbled in Disc. I thought i would present a few basic ideas
Would love someone with the time and patience to run with this and elaborate on it
HOLY
You guys can keep that, have not played it enough to give it too much thought.
This should be a solid healer, no shadow spells at all
DISC
disc should be given Shadowform, the ability to switch in and out of shadowform exactly as shadow does now
depending on which form your in the spells take on different form
e.g.
Mind flay / Penance would only be available depending wether you were in shadow or not
so in shadow mind flay is available and it deals 70% damage, 30% healing (Flay would not be channeling, it would act as penance cast, 3 hits, etc)
not in shadow penance is available and it deals 70% healing, 30% damage
this would similar for all spells, theyd of course need a rework / renaming, but all with the 70/30 difference in healing and dpsing
Mind blast / Flash Heal
dispersion / bubble
shadow word pain / holy fire
SHADOW
would be in constant shadow form
would lose all holy spells
but gain the ability to leech like old Vampiric touch in order to get its heals off
