RE# 995, why do you people insist on bringing up 4E over and over and over and over? Janx (in #954) didn't say anything at all about 4E, and he didn't restrict "roles" to combat--he just observed that fighter/cleric/thief/magic user is a sufficient adventuring party to handle most challenges in
adventuring. You're correct to point out that 4E focused exclusively on only one part of adventuring (fighting), but how is that in any way germane to Janx's observation?
Janx said there are situations where
fighting/thieving/clericing doesn't cut it. Isn't it pretty obvious that he's not talking exclusively or even primarily about combat? What can wizards do? Well, for one thing, they can summon Phantom Steeds for everybody to ride on the overland map. That isn't thieving, fighting, or clericing, and yet it's valuable.
But, alas, people will still conflate 4e roles with class and character and the arguments go round and round.
In this case, the argument is going round and round and round because someone injected 4E into the discussion, apparently to try to revive the argument just when it was moving back to 5E.
Obligatory 5E roles observation: I maintain that "grease man" is a pretty excellent role to have someone in the party play. A grease man gets you into places you otherwise couldn't get. How you do it doesn't matter: a druid could polymorph everyone into spiders via Animal Shapes; a sorcerer/bard/rogue could fast-talk you past the guards with some combination of illusions, Enhance Ability (Charisma), and Expertise (Deception); a wizard could turn everyone invisible and cast Passwall at the crucial juncture. My players last session avoided some killer fights by virtue of the Shadow Monk's
Pass Without Trace ability on their way to the fortified enemy temple. Unfortunately someone wandered away from the grease man halfway through and then a huge enemy patrol
did spot them...
