1. Holy avenger + tyr's deliverance (behind a pillar before the first cc chain starts).
Dont precast Cooldowns ever unless you are 100% certain they are needed. Starting off 3s Arena as Hpal is pretty simple. Against rogue comps try to get infight by using shock/judgment offensively from afar, or if one of your teammates goes infight first, just get a shock off on them. Then you just start the pillar game. LoS enemies, keep your teammates topped. Arenas are all about trading CDs effectively, so youre always doing good if you have to pull major cooldowns later than the enemy team, or not at all. As for Avenging Crusader, you can dive in as soon as your mates start taking dmg, pop wings and do dmg to heal. Always be aware about your positioning though.
2. Aura mastery(w/ devotion aura) when my team is chasing someone around a pillar and I can't afford to follow them around.
Not only should you use the Devo Aura Mastery only when big damage is incoming or the enemy team pressure gets too much to counterheal, but also you should try to line AM with heals as it alleviates all healing done on everybody who is affected by 15% for the 8 secs duration. Heavy dmg phases where you juked the enemy allready and they cant cc you atm, you can pop Tyrs + AM and youll easily outheal the dmg. They take 20% less and you do 35% more healing. Pretty big.
3. Divine favor to get a strong heal off, if I really need to, I also pop my wings here.
This Tier is really dependant. I personally wouldnt say Divine Favor is a necessity. I play Avenging Crusader and with Defender of the Weak + my Beacon i almost got 100% uptime on the 20% haste buff during heavy dmg periods, which makes me hit faster and have lower gcd which translates directly into more heal as Offensive Wings User.
4. I put a hand of sacrifice on my teammate if I see a long CC chain coming. BOP if the enemy team does not have any purgers/castercleave.
You should in my opinion never pick any other talent over Ultimate Sacrifice, and just like Xonika pointed it out allrdy, its not used to counter CC on you anymore as it transfers 100% of the dmg the target takes onto you in a DoT Debuff. Which is really easy to counterheal. So if your enemies start bursting hard on one of your mates, you just SaC him, go behind the pillar and conveniently top yourself against it. EDIT: Even against castercleaves you can BoP btw as castermates dont suffer setbacks from pet attacks f.e. and if the enemy healer has melee CC (legsweep,paralysis f.e.) then it doesnt go through aswell. Just be hesitant against mages if you got melees on your team. Nn to supply em with free bops.
Im actually a Ret Player, just started playing Holy this season, sitting at 1,9k in 2s and 1,8k in 3s atm so we are pretty much in the same boat. Be aware of the possibilities these new abilities give you. And dont stick too much to a fixed pattern but rather use your CD's situational. Also PvE helped me a lot to get routine on using these new abilities. And watching better Hpal Players doing their thing: https://www.twitch.t...good/videos/all
