This is just a random musing, nothing more.
I do believe holy palas need a few more tricks so that we can
a) Have more fun healing
b) Heal in a comparable way to our counterparts, ie Priests, Druids and Shammies.
I seem to be the only person in these forums who likes Beacon of Light, but then again I haven't played holy for a long time and thus don't really have an informed opinion. But the one thing I like about that spell is that it feels different from other heals.
I think it's important for spells to feel and look different and that's why an idea for a new spell ocurred to me. The spell could be called Guardian Angel or Divine Protector and the mechanics would be that "Summons a Guardian Angel to heal target for 30 secs. Cooldown 3 mins". Guardian Angel would have its own Mana Bar and while summonned clicking on the spell would cast FoL (scaling with caster's own Spell Bonus) on target NOT sharing GCD with your own heals, which could be targeted to other party members. Combining this with Beacon of Light would be like having 2 healers on Tank while you healed the rest of the raid.
This healing spell would allow caster to heal more targets whilst making it harder on him too, ofc. It'd feel different from other healers, and it would have a nice visual component to boot.
Just an idea.
