Just a little insight, with colo weapon and a few colo gear and the rest RHD, all 3 of my dots fully ticked kills a level 50 mob. So I cast 3 dots, target next, 3 dots, and repeat while keeping myself alive as the mobs hit me as they die. I end up killing 5-7 mobs at a time. If i try spamming holy light, it still takes 2-3 holy lights to kill 1 mob.
Dots still play a major role in your KSing ability. All 3 of your dots tick at exactly the same interval.
Ray of genesis is still a multiple hit skill, Having 3 dots + all those ray of genesis dmg amplifies your chance to secure the kill with all those dmg ticking during that short period of time your RoG is doing dmg. Rare occasions does someone die to your dots running away but it happens. If you add ArchAngel to the mix then...yeah..even better.
If you pick up no dots for pvp, then you're solely relying on KSing someone someone else has already lowered and trying to kill someone anyway.
I find it more consistent to find a squishy target like a sorc/wiz or ranger and dot them up, hit them with a few holy lights and finish them off with my RoG at 30% hp.
Priest can 100% to 0% sorcs/wiz and rangers pretty damn fast with the right build and finding someone who's too busy fighting someone else is not that hard to find. This is assuming they're not stacking buffs and potting on CD.
So if you're even considering any points into HL, then you might as well commit to picking up your dots instead. If you're starved for points, you can take points out of sacrement. If you wipe on a boss, the reason isn't going to be because you did 2-4% less healing. On paper it would be nice to have for sure but realistically, its marginal.
