Hell, made a rather large edit to my last post, only it being deleted due to me being silly and browsing backwards. Happens.
I just read, again, that Blizzard are happy with the way Retribution Paladins are, currently, threatwise, what they want them to be, is "Support" class.
This is quite vague I have to admit, so it let's each of us translate "Support" however he wants.
Personnaly I think that "Support" for Paladins should be DPSing, at least above the tanks, while healing, not on par with full healers of course, and being able to heavily buff everyone around in addition. I was thinking somewhat in the way of a Shadow Priest, but less damage, more buffing.
If Retribution Paladins are to "Support" the tree must be changed. Currently it looks like a tree that only increases personnal damage, and buffs it's party to some extent. If Blizzard wants Retribution Paladins to off heal, give them off healing talents. If you want them to buff, give them more/stronger buffs/debuffs.
For example, Improved Blessing of Might and Improved Judgement of the Crusader can both be gained with an investment of only 8 points. Also Vindication, not sure how effective it is against bosses, 5 man or raids.
Also, there is not a single talent in the tree that improves healing(Well, you may say Crusader Strike helps keeping someone else's Judgement of Light/Wisdom on, but that's plain silly). My point is, that if a Retribution Paladins is supposed to throw a heal here and there as part of it's rotation, those heals MUST count, it's nice being able to heal for 2196-2446 damage with a 2.5 second cast spell(every Warrior would kill for that), but when tank has 18K health, and takes more than that every hit, those heals will not count in the large picture, they are just not time efficient enough, nor are they mana efficient, which should be addressed as well, therefore such "Spot heals" will more likely put a huge strain on the Paladin's mana pool and not give the healers any breathing space. Maybe a talent to transform attack power or +spell damage into more +healing(which in turn, will not be transformed into +spell damage in 2.3), pretty much like the Enhancement Shamans get in 2.3. Another problem with healing is threat, even though a heal will only give 25% threat(being a Paladin), it still gives threat, which Retribution Paladins have hard time keeping low as is, granted, a 4K heal light will only generate 1K threat over 2.5 seconds, for 400 threat per second, but if the numbers Tommyguns gives are accurate(him making ~500 DPS because of threat limitations) this will not give the Retribution Paladin alot of threat breathing room. Maybe an ability that gives the tank the threat of healing? Like Prayer of Mending?
Retribution Paladins are limited by threat, and might be limited by mana as well I guess, if Blizzard wants them to "Spot heal" they should be able to do so without it playing on their biggest weakness, and on a lesser one(or at least make a weakness where non was).
Selverein said that the change Tommyguns suggested is not viable, because every Holy/Protection Paladin in a raid can add it's own Judgement, and therefore it's unneccessary to give the Retribution Paladin ability to put more than one on, I agree with Selverein when it comes to 25 man raids, but in 10 man raids and parties, you'll rarely see more than 2 Paladins. I think it's 100% OK to have a talent that is not amazing for raids, but is very nice for solo/parties, many talent trees sport this.
Another change that might be nice, is to allow the Retribution Paladin to give targets 2 blesses, but second being weaker(half the ability, maybe quarter), will give them some more buffing power. Or maybe a blessing of their own?
Again, the tree doesn't look like a "Support" tree from my point of view. If that is what Blizzard wants, it needs a major change to allow it.
