As Itoock said, too many threads on the same thing makes posting, and reffering to posts a pain, anyway, I remember somebody proposed something about zero casting time heals. Honestly thats not a bad idea, make an AA that lowers the cost of heals by 10% per rank (50% at rank 5), and reduces casting time by 20% per rank (zero cast time at 5). This would affect all heals (single, ward, sacrament, group). This way when we are tanking, and get hit we can instantly recover hp, rather than casting, then getting interrupted, then recasting, and once it finishes, we are already at 100%, so we wasted power, less it was the ward.
Hmm, now that I think about it some more, why not just have a "Hero" AA that reduces the power cost on EVERYTHING by say 30-40% at rank 5, and makes ALL casting times zero. With that, we can instantly react to damage thereby reducting the amount of damage we essentially take, while getting more aggro for ourselves, and can last longer due to a reduced power cost.
As far as unbalancing us compared to healers, hmm, well I could be general, but thats gonna take to long, so im gonna do numbers.
Fervent Aid m1: 864-1056 with 5s recast and no cast time: 192 hp/s
Devotion m1: 1376 with 15s recast: 91.73 hp/s
Prayer of Consecration m1: 876-1071 with 7.5s recast: 129.8 hp/s per target
Reverent Sacrament m1: 2099-2566 with 300s recast: 7.78 hp/s
So with no casting time, if we spammed all our heals as they came up, and all were used to thier utmost ( no 1k heal on a person down only 300 hp), we would achieve 421.31 hp/s. In contrast, a templar using a master of Glorious Intercession (to its maximum extent, target is hit 5 times within 8 seconds and the heal goes off for its full effect) can put out 301 hp/s. Add in Dire Intercession for another 224 hp/s and we are easily outhealed by only 2 spells, so I wouldnt say that we are going to be imposing on healer territory.
(If anyone is curious as to how I get the templar numbers, I took the min heal+max heal, divided by 2, multiplied by the number of uses, and divided by the cast+recast time)
