How far have you gotten on the warrior this time around? Also, what spec/content are you looking towards?
I’ve always played warrior main, and sometimes paladin alt. With the paladin, I’ve come to just think of him as a healer who is basic, but tough and effective. In melee combat (dps/tanking), I’d typically prefer to be on the warrior because I enjoy that toolkit and playstyle better compared to ret or prot paladin.
Paladin healers start out kind of sparse, but once you get Flash of Light at 18, an identity starts to emerge. You’ve got nice buffs for everyone in your party, emergency cooldowns, and a very efficient flash heal that you can spam to keep everyone healthy.
Firstly, until you unlock Greater Blessings (so basically until you’re 60), you’re responsible for buffing everyone in your party every 4 minutes or so, and you want to be timing that rebuff so that you’re not having to do it while you’re also healing. So prior to and entering combat, you’re making sure that everyone is buff, healthy, within range, and that you’re well-positioned and aware.
During combat, I assume that I’m going to be spamming a downranked FoL on every global, so I’m mainly just focused on prioritizing which targets they’ll go on. If the heal isn’t needed at all, I’ll cancel the cast. One thing that’s unique about paladin healing in Vanilla is that all of your heals are casted manually and individually (the only exception to this is tiny passive heals from Judgement of Light). When the whole group starts taking damage, it can get tricky because your multitarget throughput is limited by your GCD and cast bar. My understanding is that it’s common for raiding paladins to be mainly responsible for just healing the tank.
So you’re riding the cast-bar, pulsing FoL, anticipating where your next few heals need to go and whether you’ll need to uprank or cast a big Holy Light to catch up. Beyond that you’ve got things like Cleanse, Blessing of Protection, Blessing of Freedom, feeding lock life-taps, and situational Judgement debuffs, which are all things that can really help your party if you use them well.
One drawback to paladin is that it does sometimes have a stigma that it’s a second-rate healer to priest, but if you’re intrepid and on-point, people will definitely notice and you can make a huge difference for your party.
