Clerics;
Ancient: Hallowed Light -- this is the clerics big heal. it has a 3.8 second cast time, and heals for 4150 by default. With foci this heal goes up to about 8k non crit, 16k crit and it has a 775 mana cost. Once players reach SSRA gear level then the heal becomes less effective.
Recommendations:
Tier 1: 5000HP, 890 cost
Tier 2: 6000HP, 1k cost
**To go along with this, I'd also request changing the cleric ToV BP foci to an effect which decreases the mana cost of this new heal, rather than AHL.**
Complete Healing -- Perhaps the upgrade could be called Improved Complete healing or something of that effect. As AHL, I also recommend this being available to players on the ToV level. Right now CH does a 7500 HP heal -- 9500ish with foci. Tanks have too much HP and it is nowhere near a complete heal -- it is more like a 50% heal nowadays unless it crits. I would recommend boosting it to a 10 or 12k heal and boosting the mana cost accordingly (instead of 400 mana make it cost 500 or 550).
Recommendations:
Tier 1: 8800HP, 460 cost
Tier 2: 10000HP, 520 cost
Pious Remedy -- This is the quick heal clerics get. It has a 1.8 sec cast time, 495 mana cost, and heals for 2k. I recommend doubling both the cast time as well as the mana cost to make it effective. 2k, even as a crit, does nothing for anyone in SSRA or later. If you double it, I would recommend making it on the ToV level. Alternatively, you could boost it to 3k and make it available in ssra and then 4k for ToV. I think the alternative would be best tbh. Even in ssra this heal did nothing for Jeido.
Recommendations:
Tier 1: 3k heal, 745 cost
Tier 2: 4k heal, 990 cost
Pious Elixir -- This HoT needs a boost -- it heals for 1170 HP every 6 seconds. With foci it can last up to a minute (almost), so even if it lasts a full minute it only heals for 11700. Perhaps in ssra you could make it heal for 1500, then in ToV 1800 or 1900 per tick.
Recommendations:
Tier 1: 1500/tick, 1170 cost
Tier 2: 1800/tick, 1460 cost
Word of Vivification -- Group heal for clerics. It heals 3800, cures minor poisons/diseases. It is pretty much ok, but it still doesn't top off DPS like it used to. If a DPS is below 60% it will not heal them fully. I recommend a boost up to 4500 with a high poison/disease/curse counter than it currently has. Mana cost would need to be scaled accordingly. I would guess a change from 1357 to 1500 would be appropriate for a 700 heal boost, but im not sure.
Recommendations:
Tier 1: Fine
Tier 2: 4500 heal, 25 poison/disease counter, 18 curse. 1600 mana cost
HP buffs, etc:
Conviction, Hand of Conviction: They badly need a boost in how much they raise HP hehe. 2k HP isn't what it used to be

Maybe on the ssra level it'll boost HP by 2700, then ToV 3400?
Recommendations:
Tier 1: 2700HP
Tier 2: 3400HP
