One of the complaints about the downranking change is that Holy Paladins now don't have enough heals to do their job. I think this concern is overstated, as we actually have more options in Wrath.
Upgraded (you should take a second look at these):
- Judgement of Light - JoL now scales, and actually does a fair bit of healing. Additionally, Judgements of the Pure now gives a nice haste bonus for Judging.
- Holy Shock - Blizzard is really pushing Holy Shock. The cooldown has been dropped significantly, it's decently powerful and reasonably efficient. It's falling somewhere in between FoL and HL at the moment. In addition, if HS crits, you get an instant Holy Light with Infusion of Light.
Some posters at EJ are proposing that Blizzard intends us to melee-heal. Essential heal with Holy Shock and then sit on the instant HL while regenerating mana with Seal of Wisdom. We would do this instead of cast-cancelling Holy Light. I'm in the odd position of arguing that this is not intended, as you can't melee-heal with Holy Shock unless you mouse-over macro the Holy Shock.
Still it's a possible option, and even without the melee component, sitting on an instant HL instead of cast-cancelling has a lot of potential.
- Hand of Sacrifice - Adding this one for completion's sake, the fact that Sacrifice no longer removes Blessings makes it a far more useful option.
- Beacon of Light - An AoE heal. Not very impressive yet, but hopefully will be tuned up.
- Sacred Shield - As this is a level 80 spell and not available in Beta, this is the big unknown in paladin healing so far. If it scales well, and if Blizzard fixes the issues with rage/mana generation and shields, this could be powerful.
We do have a lot more options for healing in the expansion than we do now. Maybe not as many as a priest or druid, but I think we should have all the tools we need.
