I’ve had the opposite experience in the last few weeks.
Fully geared MW on beta at the moment for me is doing 20k DPS hitting TP and BoK on packs with FLS. SCK does more than that but requires more mobs and no healing to be done. Single target MW DPS is very low. 4-7k for most bosses for me and even less on bosses that have anti-melee mechanics.
Fully geared Rdruid/Hpal/Pres are doing similar damage on normal packs as MW, but significantly more on larger pulls and do significantly more single target damage.
If you’re pugging keys on beta and playing them like normal where you’re slowly pulling pack to pack without anything special going on and you’re healing random damage and accounting for random mistakes that the group makes then MW is quite comparable and good compared to other healers.
If you’re doing keys with well coordinated groups that pull big then Hpal/Rdruid/Pres do way more damage, especially when there isn’t much random healing to do and they can use all their resources and globals on damage.
As far as the actual gameplay for MW goes; I’d put in the highest tier. FLS is fun. Fistweaving is fun. Working around instant Vivify procs is fun. Getting so much synergy working between abilities like ReM proccing Env or RSK creating a ReM feels great.
