Bored so ran numbers 60 Druid vs 60 cleric heal

[Troxx]

Assuming cleric only casts cheal with average land of 2500 vs Druid casting 60 heal (978). Both cost 356 mana to cast. Druid has potg and mask (+9 mana/tick) cleric does not. Druid has clicky group regen bp (2.5 hps to each person). Uptime fight healing:

No clarity:

Cleric averages 24.6 hps (heal per second)
Druid averages 16.2 hps plus 2.5 hps to whole group (28.7 hps potential)

C2:

Cleric averages 37.5 hps
Druid averages 21.3 hps plus 2.5 hps to each group mbr (33.8 hps potential)

Clerics are obviously better but Druid doesn’t fair that badly. Druid heal casts almost twice as fast allowing for fewer Med tick losses.

Why don’t we see more 60 druids healing groups other than no Rez?

Ps: Torpor Shamans beat them both over time in spades.
