So after having played with holy power on the beta realms, we decided to ask our Twitter followers if they had any questions or concerns about this new system for us to look into.
Short answers: Currently, every 3 seconds for ret, 4 seconds for prot, and 6 seconds for holy due to the abilities and talents they'd be using to earn it. Usually, three points is the most efficient. It's a secondary resource, like runic power is to runes on a death knight, and there are certain abilities that use it and other abilities that have nothing to do with it.Soranomaru asks:
"How fast does it accrue? How do you spend it effectively? Is it a mechanic to empower spellcasts or another ressource like mana?"
Long answers: Holy power is a secondary resource that you'll have along with your current mana bar. As retribution and protection, you'll be using Crusader Strike to build up your holy power points (HPP). If you're holy, you'll still have access to Crusader Strike, but you will also be using Holy Shock to build up that HPP. The most HPP you can build up at a time is three, so you'll be earning and spending fairly quickly. Some abilities give a flat rate based on how much holy power you put into it (Word of Glory), while others get much more efficient with the more points used (Templar's Verdict).
