Blizzard really needs to fix the requirement for (Shadow-)Priests in any high M+ key this season.

Massdispell is basically (especially in a bursting week) a requirement just like bloodlust and CR. The fact only priest have it, together with their Top-3 DPS and having Pi lead to a ridiculous amount of SPriests the higher the key level.

Some stats from raider.io:

M+20 and higher (timed)

• 10.2% of all DPS are SP (#1 is FOTM retri pala with 12.3%)
• 20.0% of all range DPS are SP

When bursting week:

• 14.9% of all DPS are SP
• 29.1% of all range DPS are SP

M+25 and higher (timed)

• 25.9% of all DPS are SP
• 48.3% of all range DPS are SP

When bursting week:

• 29.5% of all DPS are SP
• 52.8% of all range DPS are SP

I think granting a MD-like ability to the underrepresented classes (especially to those without BL and CR) would really help this situation.

But maybe I'm overreacting and its not that bad. What do you think?
