balance out by the fact that they dont lose any piety by not fighting which I think will get harder with patches especially against the turks and fatamids.
Try playing Byzantium and say that again.... To take a not entirely hypothetical situation....
The difficulty in gaining piety makes the Regal Supremacy random moneylenders/merchant houses/&etc events (-25 piety apiece) real killers as they tend to hit in waves as the prerequisite tech spreads, assuming you have a few demesne provinces - which is not unlikely.
The agony of gaining BB from dowing muslims [okay, I am afraid the hypothetical attacks counted as sneak attacks

], then
finally gaining piety by appointing bishops (one of the few options open for the orthodox) - only to see the piety wiped out by a wave of usury events is indescribable.
250 piety gone in half a year. WAAAAH.
Pretty soon all your vassals are becoming disloyal and there is no end in sight to your BB. :rofl:
Seing Byzantium fall apart because of succesful wars against the infidel coupled with usury is rather silly.
(Well, one
could, of course, switch to Monastic Supremacy or Ecclesical Balance just like everybody else, but then it is not really Byzantium, is it?

)

... Even if the hypothetical player above got what he deserved, -25 piety per usury event is an awful lot, as it is nearly impossible to prevent them and as it is incredibly hard to gain piety as Orthodox. I have taken to halt whatever is being produced and giving orders to build the relevant building whenever the prerequisite tech appears in a province, as the piety hit is smaller when you build it yourself. It is a race against time.

The most abusable way to gain piety as Orthodox (and it is an awful lot of work and not guaranteed success) is to appoint a 1-province bishopric with a small army in a poor province next to the muslims and hope that the muslims conquer it returning the theologically trained ruler to your court, allowing you to reconquer the province and create a new the bishopric.
