I know why group A doesn't want super-buffed fighters unless they're supernatural somehow.
And I know that group B wants fighters to be just as gonzo as the wizards.
I've forgotten why either group cares if there is no decent mundane fighter option, and all the good ones are supernatural somehow.
Anyone care to say if they are A or B and if they hate the balanced-with-wizards /gonzo fighters needing to pick a power source like demi-god, ancient mystic heritage, secret inner power source, dipped in Styx, blessed by the gods, etc ..?
I prefer player options that are supposed to be roughly equivalent, equally viable, etc to be mechanically on a par.
How that is done mechanically, and how that relates to the fiction, can vary.
In my second long-running Rolemaster campaign - which followed on one where, after about 10th level, all the players drifted to playing casters - we reduced the power of spell users (by reducing available spell points) and buffed warriors (by increasing the range of fighting style-type bonuses). The rough intention was that, in sheer power, a nova-ing caster was comparable in effect to a warrior. It worked, more-or-less.
In 4e D&D, we had no issue with this. The fighter was a mad powerhouse alternating between his axe-headed polearm and his massive Dwarven maul. By epic tier, his jumping distance was around 50' I think. One time he jumped onto the back of a white dragon, pinned its wings, and rode it down before jumping off at the last minute.
Burning Wheel and Torchbearer are pretty much the opposite of this - neither warriors nor wizards are gonzo. As I posted in another recent thread, in eleven session of Torchbearer the only magic-using PC (an Elven Dreamwalker) has tried to cast a spell
once (and failed, hence summoning an evil spirit instead of conjuring a floating disc); otherwise she contributes by reading runes, tricking the gullible, healing, and generally being useful. She will be the first of the PCs to reach 4th level.
I will agree that a direct hit by a fast travelling 2-ton boulder also feels like it should be lethal to an unprotected mere mortal, no matter how Conan-esque they are. Is there a mechanic that has the boulder hit in that way and not, say, just go grazing (relatively) gently past then?
If the boulder more-or-less fills the corridor, and the PC is at a dead end, don't they (at least by the rules) still get a Reflex save, get to use Evasion if a rogue, etc?
