I can understand the resistance against turning healers into support DPS, and instead wanting the healing itself be intense and engaging, but I've yet to hear a single realistic way you could rebalance the game to work like that. Hugely trimming down the healing kits and replacing them with a decent DPS rotations is pretty easy thing to do as top-down change, to make things more in line with how healers actually spend their time. But going back and rescripting 8-10 years worth of encounters so you have to actually spend even half your time healing seems like a pipe dream.
