Your assuming Pathfinder even pretends to be realistic. Which it really isn't. And I don't want Saitama, and the examples I've given (Paths of Wars, Dark Souls humanoid enemies) are nowhere near Saitama. I already posted some examples of maneuvers from Paths of War, and none of them are OP compared to a caster's spells of that level. I'm not even arguing that Martials should be able to create demi-planes and so on, just be as good if not better than the wizard at the job they were supposedly designed for.
Also, the Balor takes ten hits to kill from terminal velocity. My question to you is, how many hits can a Fighter kill it in? Assuming no friendly buffs from the Wizard?
Well, if you don't want Saitama, or even the Naruto-level "rearange the countryside with your punches" sort of craziness, then I probably don't disagree with you. I also think that the Fighter could use some buffing, as I mentioned in that post myself. I only disliked how people were jumping on The Sword for wanting to play a level 20 character that didn't have all the crazy powers that were being claimed as part and parcel of that level of play.
As for how many strikes it would take the Fighter... well, I'm not a Fighter expert, so I'd have to defer to those who know that class better than me if you want a really optimized answer, but supposedly there was a Fighter build up-thread that could do it in one hit. I didn't look too closely, so take that for what it's worth. 200HP per round was also thrown out as a benchmark, IIRC. *shrug*
This entire post falls apart when you realize that terminal velocity is not that significant of a speed or force. It's roughly 122 MPH. A bullet moves much faster. An ARROW achieves almost precisely double that velocity, at the low end.
The arrow is also going to have a higher force output than even a "fall" of the same speed, because the fall is going to spread damage equally over the entire surface area of the impacting and impacted objects, where the arrow compresses all of that force to a single, much smaller point.
Yes? I'm not sure I follow what your objection is. I didn't mean to say that the fall and the arrow had the same speeed, and certainly the surface area aspect gives an arrow or a blade an advantage in penetration and getting to internals for more effective damage to a creature. That advantage doesn't make the point of the post fall apart, it makes it stronger, since the force compression allows for greater damage efficiency on the part of the Fighter.
The fact that terminal velocity is, as you say, "not that significant of a force" is exactly the point. The point is: "if a CR20 Balor can be substantially harmed by 'merely' hitting the ground at 122 MPH, then why would we insist that a Fighter needs to have "devastate the ecology with his weapon strikes" levels of power in order to fight it, or other CR20 foes?
The Fighter needs to be strong, but he doesn't need to be that strong, not by a long shot.
