Yes, I agree, that fullheal is too spammable, and think that it should get a longer CD, but I also think that if it does get a longer CD it should be balanced with a slightly reduced cast time as it already takes 25% of the Clerics mana.
- CoolDown increase to 40 seconds
- Warmup decrease to 3 seconds
I don't know that I agree with dropping Divine Blessing that much, it's scaling with 40 Wisdom is 250 AOE(Max 5 person) heal. It's scaling is so high because it's base healing was reduced by 50% with the introduction of attributes.
Holy water currently only heals for 135 with 40 Wis, but honestly I feel that is where it belongs. It's instant cast, reletivaly low mana and 7 block radius which is pretty good.
Guardian Angel is a very strong spell but it does sap a lot of mana and is generally only able to be used once, maybe twice in a fight. This would be hard to change without destroying it. One thing that might work and would switch it from a "big play" to a "setup" skill would be
- CoolDown decrease to 45 seconds
- ManaCost dcrease to 200
- Duration decrease to 1.5 seconds
I agree that all revives should be on a longer cooldown, but until GTP is fixed to have a 5+ minute timer prevently recently revived players that this is a worthless change(Except in tournaments.). Perhaps eventually change it more in the area of 3 minutes. You want to be able to perform them, and this should limit it to 1-2 per fight. I would not suggest making this change until GTP is somehow restricted though as it's far superior to revive and is only on a 5 minute CD
