As a harmonic saint I'm gonna go out on a limb here and say the ability to get 10k points in a millisecond and then have it be capped so I'm stuck uselessly throwing hailstorm at the monster and not incentivized to heal my fellow raiders is quite unfun.
Attacking the black or white dragon has a 2.3 MILLION point limit. Why is healing not treated the same way? It's not as though its useless considering the very wide AoE of attack, and healers are always thanked by players but the system itself is quite unforgiving and pushes dps above all else.
All being said, I propose to raise the limit for healers and even other forms of assistance, such as killing small mobs.
