2. Putting aside all the answers author of this topic got - the whole discussion turned into Intellect Paladin vs Haste Paladin. Lay says that Haste is superior in healing output to Intellect Paladins, simply due to the fact that in the same time it will take Int Paladin to cast 5 Holy Lights, Haste will cast 6 HLs, so even if Int heals for 3k-4k more per cast, Haste will still be ahead by a lot, which is vital on fights where tank takes dmg equal to 60% of their hp. Moreover on fights like Halion, where flames are bugged and their spreading is so different from their retail equivalent faster casting is very important. Here is a proof of how flames should work and we all know how they work now:
1.
Proof nr 1 (Paragon Kill) they still resemble the X shape even if slightly off
2.
Proof nr 2 (TankSpot Guide Kill) their curling is nowhere near as extreme as it is on Warmane
So obviously people will get hit by the flames, once or twice if they are fast enough and that's where the other difference in healing by Haste and Int Paladins shows - you can get them to full hp, before the tick kills them most of the time, while the slower casting paladin will fail in some cases. And I'm not talking about picking them up with Holy Shock and Instant FoL, because that can be on cooldown if you used it on someone already moments ago and the other might not proc or simply 2 heals won't be enough if more people got hit.
