Ever since the the spell system change of 0.31 I've been pointing out that since Grigori Medics can start with a religion (there is a 20% that a unit without a religion to get any given religion in the city that builds it), and always start with Divine and Channeling 2 & 3 (the prereqs for Cure Disease and Heal, but also all high priest spells) they are probably the biggest exploit in the game. I've been suggesting that they loose these promotions and that Cure Disease and Heal be made to require the Medic II and III promotions. Kael has consistently ignored me on this issue, so I assume he must like this exploit.
If he doesn't want to change the prereqs, maybe making the Agnostic trait prevent the leader's units from getting a religion would be a good idea?
Magister, after you posted about this exploit, I ran a little test as I was playing the Grigori and my game was in its final stage.
After I built the Eyes and Ears Network I got the disciples, etc. for all the religions - another Grigori exploit IMO.
I was able to spread FOL, ROK, CoE, Empyrean, and OO in my capital where I was building all my units. The Order and AV failed to spread.
I built 50 Gregori Medics and here is what I got:
7 FOL
5 ROK
3 Empyrean
0 OO
0 CoE (not sure what that would have been)
35 No affiliation (I deleted those)
So, it was better than 20% and adding 15 of those units to my army was significant. However, the main things I used them for was summoning Tigers (one allowed me to build the Grand Menagerie as I was missing that animal), Shield of Faith for all of my units, and, of course, the powerful Crown of Brilliance for weakening those attacking stacks I mentioned in the Super Stacks thread.
Should this exploit be canceled? I'm not sure as it does take a while to get Medicine and build them. Then, you have to have religion spread to your cities to get the affiliations. If you can build the Eyes and Ears Network (later game), that would help too.
