I apologise, this is less of a question, more of a rant/defense.
I give you the bottom line first:
Yanking Specialisations from medical is mindboggingly bad.
It doesnt scale. Healing will fall behind in damage every single time for the same amount of Rank/CP.
Since both negative removal and healing are rare specialisations, i would need 2 different +elements (at the least) to do the same thing... and they would be uncombined. Thats 1 PP more i have to spend to do what it does right now, and even then its worse.
Yes, you "unlock" the table, but that is a meager win if you dont get the possibility to use it.
-Unless- you then make it accessable that the medical table can be used in favour of other tables when it gives a better bonus: Which makes it ludicrously overpowered.
Any fire-user (or any +element, bloodline limit and so on) with specialisation in damage is 1.5 more effective than base healing at this point, forever.
Medical Shinobi who use 1 power point to unlock the table at base will always and forever be behind the damage/healing ratio random person nr 17 can do at same rate. Random person nr 17 uses an A-rank with 1.5 damage per JP, just straight and plain. Medical Shinobi heals with an A-rank with 1 healing per JP. Whichever scale, the medical Shinobi will always loose out in the long run, since it is improbable to do the same amount of healing than the random enemy will deal.
Even if i at that point use all my PP on being as effective a healer as possible (bring my specialisations back, more targets, more healing and so on), i still have used 1 PP more than the one who did the same build (specialisations, more targets, more damage and so on) for damage.
Bring back/Do not remove Medical Specialisations. If dealing damage swiftly is the only reasonable way to go and it costs less PP to do it, so there is more to specialise in more damage/accuracy/targets, then i shudder to see this going down in a large cluster of more and more specialised people with one-trick amounts of damage which will sure-fire give them victory.
