okay but power creep by what scale?
if a ranger (the common easy target) or monk (slightly less common but not by much) are a 4 on a scale from 1-10 and the druid is a 9, then is bringing the ranger and monk up to a 7-8 power creep when it is still lower then the druid? Is giving out expertise to every class (like say all fighters are expertise in athletics, all mages arcane, all clerics religion) but keeping bard getting a few and rouge getting a few moth then bard they can put anywhere (and in the rogue case included in tools) power creep or equalization?
if we change fireball to doing d4's (yes I know never going to happen) so that no other 3rd level spell is out stripped a nerf or a rebalancing?
