First thing to mention is, you gave no answer to the "reward" Q.
May I insist? Which rewards does your CC gain from your industry?
IMNSHO your CC needs no CC XPs. Thus I'd not care for any extra points from costly passes.
Analysing this "CC passes" thingy and watching myself, it's highly astounding how much (and illogical) we are prepared to give for the community.
This thingy appears to me as our host's credit-munging "pay for nothing" business plan with a blatant disproportion to the detriment of the CCs and their members. See through it and your ambition may drop dramatically.
My personal rules:
NEVER spend credits on passes,
NEVER use one in a MP game,
one essay to give the CDP bonus XPs to the CC is enough. If it fails, try again tomorrow,
one free pass per day is enough, one hole = 900+ XPs vs. 9 holes = 230 XPs,
I play the CC clashes for fun in unison with my friends, not to win anything.
As always, to each his own fun!
