I can see different spells of similar nature stacking from the same caster,(multiple stamina replenishes etc..) or the same spell w/2 different casters, say two priests consecrate same ground stacks, but the same priest consecrating the same ground repeatedly, effectively negating stamina in combat completely seems to me like this is not what would be intended.

You're right, effects from the same source stacking is not intended. We are aware of this issue and working on it.

 

Thanks for your feedback, it's greatly appreciated.
