In the DCC RPG ruleset, many have noted that Wizards are given an extraordinary level of awesome, whereas Clerics sort of get shafted. A huge amount of space is dedicated to Wizard corruptions, spells, how they find spells, and Wizard patrons.
Clerics have fewer official spells, all the deities get a single line in a table with just their name and alignment, and all Clerics for all deities are given a single Disapproval table that they always roll on. This contrasted with pages and pages of example patrons with complete flavor text descriptions, invoke patron results, patron taints, and patron spells.
In a recent episode of Spellburn, one of the hosts went so far as to say Clerics are useless, suggesting that they should just be combined with Wizards.
All of this is massively unfair to the Cleric class.
