I hate having to use PallyPower. But handing out Blessings manually is very annoying, especially if you have two or fewer paladins in the raid.
Here is an idea to make casting Blessings easier. I hesitate to propose this, because it is a nerf to paladins, and everyone is going to complain about that. (Yes, I know my audience.) However, I would rather have a reduction in power--which can be made up somewhere else--in exchange for the smoothing out of gameplay annoyances.
Suppose all normal Blessings--not Greater Blessings--hit the entire party or raid instead of individuals. There would be no more individual blessings, just one button and you Bless the entire raid, starting from the very first rank of Blessing of Might that you get at level four.
This immediately simplifies Blessings, because you can't make complicated assignments. You hand out Might or Wisdom to the raid, not Might to some people and Wisdom to others. However, multiple paladins still hand out different blessings, just like now. You could even have the regular Blessings cost a reagent and last for 30 minutes, though you might have to do some fiddling with the lowest ranks.
This would probably make Kings the first choice of Blessing, followed by Might and then Wisdom. I'm not sure where Sanctuary would fit in.
The biggest problem with this scheme (other than the fact that Blessings become less powerful) is that Blessings become more similar to Auras. A paladin gives 1 Blessing and 1 Aura to the raid, and all raid members get the same Blessing and Aura. However, Auras are still centered on the paladin and are lost when the paladin dies, while Blessings belong to the character, and have a limited duration. Perhaps that is enough differentiation. Another minor issue is that you can no longer do drive-by buffing of random people, which is always fun.
Edit: Heh, I just remembered that I already wrote a Streamlining Blessings post a year ago, which proposed combining Blessings of Might and Wisdom in a single Blessing. Guess this is another solution.
