If you make Toxikon DPS neutral you need to give it a cooldown. Otherwise you'd have unlimited DPS neutral healing.

Moreover, now you essentially lose all other GCD healing options, leaving AoEs to your cohealer for whom the relative costs are lower while you in turn take over all ST healing needs. Your co-healer pair's full range of GCD healing... is then reduced to Medica II and Eukrasian Diagnosis.

Let's assume again that we increase the healing requirements, because we certainly can do so at least a good third or so without overtaxing healers (though such still leaves too much downtime for the current state of filler-DoT-CD/spender to be a sufficiently compelling loop for most skilled players). You'll have then heavily reduced the variety available to the healing itself, greatly narrowing/dumbing that down whenever a SGE is present.
Eukrasian Prognosis can also generate Addersting when its barrier on you breaks, so SGE would also have unlimited DPS neutral AoE healing.
