I agree that its core definer needs to be improved, but I'd suggest this layout instead:
0 -0.05 0.05 0 1 0 1 0 1.25 1.1 1 1
In this instance, you've got a personality that gives a better bribe resist which is a unique characteristic, a small research bonus and a considerable improvement for its core definer, a 5 percent casualty. I'd also improve max gold research to 30 to further compensate for its crappy 20 percent spy research.
To me this gives the cleric a good, well rounded balance that provides bonuses in several areas but is master of none, which seemed to be the intent they were going for anyhow.
While I'm at it, I'd also say Archmage needs a 10 percent mili sci and master thief needs 15. Either that, or MT needs to regen 1.5 spy turns per round and drop off the max bonus to 2. (get rid of the nasty spy ops alpha strike and replace it with more frequent ops). I think it'd also be neat if the Archmage could research shield sci to 110 or perhaps even 125 to compensate on a defensive basis for its ridiculously low mili sci.
Not sure what's going on with the peasant, but boost its pop sci to 30, agri sci to 40 and give him a 15 percent bonus to peasant growth (man of the people leadership, so to speak.) This ensconces the peasant as an archetype for land managers who want to make the most out of their land and is capable of quick income and quick growth, but not a whole lot else.
Other tweaks I'd like to see:
* Barb pop sci to 20.
* War Hero mili sci to 35, .95 unit cost.
* Scholar reduced to 1.25 research.
* War Gen's mana research reduced to 30, spell cost to 1.2

Cleric 0 -0.01 0.05 0 1 0 1 0 1 1 1 1
What you're suggestion is not a good idea to me, cause it totally trashes the use of archmage if it has any. The only way to make cleric worth using is if they make the determining bonus of cleric more effective
change it to:
Cleric 0 -0.03 0.05 0 1 0 1 0 1 1 1 1
Or for the illiterate, this means that the casualty drop from clerics of 1% is boosted to 3%, making the cleric casualties kinda to the likings of the undead/CHT realms.
