Two tangents that have always bothered me are:
Why are full casters (with no real combat training) going out in situations where nose to nose small scale combat will be regular? Why aren't the full caster ones back in the wizards school or doing research? It's not like Gandalf wasn't awesome enough with the sword to take on a freaking Balrog.
Why are the clerics that go out with all that armor and spells full casters? Why aren't there some even better casters back in the temples who have passed on the combat stuff.
So, getting back to the thread...
How do the fighters feel if the Wizards and Clerics going out with them are half-casters half-combat?
Or did this ship sail way back in 1e and 2e when (as
@HammerMan and
@DND_Reborn noted upthread) the balance was the M.User having to live through the first few levels being useless with no hitpoints?
