u could try to uncomment the following lines (788,920,1117,1156) in the file VachiusaHolyPQI_Paladin_Abilities.xml and try again with EF to see if it is ever casted (if u don't have a running recount or any simliar wow addon)
i haven't tested that much so far with 5.4, it does heal for holy pally -> YES, but it does good healing -> NO
it is okay for flex raiding, cooldowns are used good, but to compare with current Holy Pally Players it should use EF much more, also Selfless Healer is not supported (i'm thinking about adding this) and Sacred Shield is now a viable option for us (in my opinion, but i could be wrong), and needs a change (instead of returning true on the first seen player with SS up, this check could always return false, since the target limitations was removed for Holy Pally)
