Oh yeah, I forgot about warlord. Warlord is also pretty OP, and probably will get nerf'd, tbh. But if it doesn't, then yeah, warfare should get a diferent bonus then the extra damage for every opponent in melee. As for blacktail, lol. Spoken like someone who's never tried to carry or swing something like that.
And you're telling me you have the experience of an actual swordsman who's trained all his life with two-handed swords? Wow, you must be attracting all the ladies then.
You fail to consider height, weight, musculature, genetics, diet and training. As someone who regularly trains in the gym, I know for a fact that slowly increasing weight and maintaining exercise with said object (taking care that you're not overexerting, which is detrimental for muscle growth) allows people to be able to carry heavier objects as training progresses. Of course there's a limit as to how many kgs each person can carry even taking into account core strength, but the limit varies heavily on the person's height, weight, musculature, genetics, diet and training. The same applies to swinging swords and other weapons. The vikings and the barbarian berserkers swung their swords and axes without a problem. There's Musashibo Benkei too, who swung large two-handed weapons with ease, killing actual fully-geared samurai with a single swipe.
And even if you decide to conveniently leave all this out, there's still the fact that you wouldn't exactly know how physically strong a fictional character (not just regarding humans in the game, but elves, dwarves, lizards and whatnot too) really is because they don't actually exist for you to observe and record.
But hey, go ahead and be an asshole.
