This is pretty much what I'm interested in as well, having a froob doc that's approaching endgame status and twinked for team healing above all (nano regain, lots of nanopool and HP to survive, debuffs and general support with personal DD a much lesser concern beyond DoT and Nukespam when not needing to debuff/heal). There's probably only a tiny handful of people who care about non-220 endgame docs though, so I don't expect much.
So, from an amateur froob doc PoV:-
Losing ghetto calm Decreptitude is going to be a pain. Cooldown timers too for the heals. Wondeirng why they switched a couple of the A DoTs into the C line but assuming there aren't typos in there, that does mean froob docs will be able to use a couple of the Cs (albeit lowbie ones) mostly for additional First Degree Burns damage (lol).
Regarding new froobable single target heals: I assume you mean Revitalizing Salve, Alleviating Remedy and Analgesic Balm which now appear higher than LE and lack SL requirements in the expansion - I hope that's not just a typo
1050 BM/MM self for a froob doc means a rethink of current endgame imp and gear strategies. Cooldown timers are a concern, especially with the reduced duration of everything else: with no perk heals to cover the gaps, CH in particular looks to be painful.
The new team heals on top of Team Health Plan don't appear to have SL flags but as Congregated Wellness is 1250/1250 and Surgical Clinic is 1450/1450, I don't think they're meant to be froobable
Invigorating Harmonization looks like it could be fun, provided there's a PNH/IOR dispenser and you can hit up kits every 30sec. (I'm having trouble seeing what exactly is the casting nanocost - has Team Health Plan really gone from 175 to 1311 per use?)
Nano regain is of particular concern, that area being one where froobs are severely lacking. A 5min emergency boost isn't going to cut it.
Enlarge/IC - double nanocost for the same Sta/Str boost as current IC is plain mean to anything lowbie
