I'm sort of confused with the healing strategy for Paladins, I'm a TBC veteran, just started playing again about two months ago. So I'm sort of struggling trying to look for info and re-learning my class. I'm noticing that I'm excessively using Holy Radiance + Eternal Flame + Light of Dawn. I'm casting almost no Holy Lights and No Divine lights whatsoever. Although at first I was having mana problems no I have good enough gear that mana is not such a big issue at the moment, now HPS is. I'm getting beaten in HPS throughput by similarly geared people. I know I'm giving no context and playing style has something to do here but I would like sort of a short healing strategy for max HPS, bellow is a summary of my current strategy for healing.
Beacon tank, get in melee range if the fight is sort of static like Sha of Pride, etc... I start to build holy power using holy shock as much as possible and crusader strike (if on melee range). I start casting Light of Dawn if there is a lot of AOE dmg or cast Eternal Flame on tanks for the HOT or for any spike damage that might occur, sometimes I start to cast eternal flame on everything that I can and I can get my HPS a bump there, in short I'm relying to heavily on my holy power heals. Practically no Holy Lights, no Divine Lights and no Flash of lights whatsoever. Maybe this is the way to go, just feel bit lost.
Thanks for the time.
Like Exemplar said CS is typically no no, you're not melee hit capped and even though it's a small risk that you'll miss it's still a waste of mana and a gcd. However, using Holy Shock on CD is something you want to do, it's super cheap, short cd and generate your precious Holy Power. Our heals cost more mana than other healers equivalents because we do have our Holy Power, maximizing HP generation and thereby getting "free heals" is a must.
Regarding playstyle, if you are specced into EF you very very very rarely ever touch Light of Dawn, the only time you would do that is if several people would die unless you heal them now, which honestly never should happen. Your typical "rotation" will be Holy Radiance->Holy Radiance->Holy Shock->Eternal Flame (You want to have 3HP EF's on tank(s) and yourself 100% of the time). If you instead go the route of speccing Selfless Healer you will cast alot of Light of Dawn, and your "rotation" will instead be Judge->Holy Radiance->Holy Shock->Light of Dawn. If you go for EF you want to get your haste to 3506 or 7170 (depending on gear and preference), spirit til comfortable and then mastery. If you instead go for SH you can get rid of all spirit basically and instead just go for mastery>haste.
A big part of paladin healing regardless of EF/SH is your cooldown usage. You didn't provide any logs so I can't tell if you're already using them wisely, but doing so is key. Try to plan your cd's ahead of time depending on the damage pattern in the fight.
