Yoshi-P has already stated that they will never increase the healing demand required of the healers.
Which is why people are asking for more dps buttons to press when we do get groups of experienced players so we're not pressing one single button for 95% of the time.I mostly do DF/PF and get in groups with new and random ppl, so i stil get to use my heals for now at least...
But when i do get an experienced group the dmg output is close to zero.. and you end up beeing a green dps.
The "I only play healers to heal" players already ignore their damage buttons, so nothing will change if they add additional buttons to press for those who want something to do.
