In a loose way, (and I mean very loose) you have somewhat made my point stronger. A "charge" is building of momentum and using that momentum to apply force to your swing, while sacrificing some of your mobilty (Do not confuse with feat). When you jump, you do slow down. The only people who don't slow down are athletes running over hurdles. A hurdle may be 3 to 4 feet high, but it's only 1/2" thick/long, not 5 to 10 feet long. Long jumpers, can actually jump the distance (possibly, I haven't seen the olypics since 1980), but no where is it possible for a long jumper to continue running at the same speed after he lands the jump, even if there wasn't a sand pit. Now picture both athletes trying to do thier respective jumps in armor.
Now, I said you strengthened my point, and in a way, you did. Changing direction while charging. It *IS* possible, but only after you taken the Fleet of Foot feat listed in Complete Warrior. The feat provides a turn of up to 90 degrees while charging. The Swashbucklers Acrobatic Charge ability falls into this again, as when you charge, you are allowing to charge over obstacles when the appropriate jump and/or tumble checks are made to bypass the obstacles.
I could see if player came to me, and said "I really like this ability of this class, but the whole swashbuckler persona doesn't fit what I envisioned for my character. Let me describe what I was thinking for my character, and maybe you can make that class ability a feat for my character to take." If his description was sound, I would probably have no problem in turning Acrobatic Charge into a feat for *THAT* character, or possibly taking away a class ability of the class he had chosen, and replacing it. Keep in mind also, the Acrobatic Charge can only be done in Light or No Armor, and the character cannot be encumbered in anyway.
If you want your point strengthened you don't have to go farther than the DMG, Duelist, where there is also an acrobatic charge.
However, so they in your opinion slow down, or lose momentum after a jump. Do you apply this houserule to every jump, or only charges?
Also, what if they ended the jump, the one jump, in the attack, that would be transferring all the momentum used up into the attack, just as you want.
OK, ok, I can see the argument that this is loose writing, and should be house ruled. On the other hand, that makes it officially unofficial, as by the writing it clearly says the opposite... well, for a given value of clear. You have to look at what an obstruction really is, and realize that the jump skill, as written, completely negates some things that would otherwise be obstructions from the realm of an obstruction. Hence nothing to stop them from charging if they make the check. At least, as written. And I'm arguing striktly RAW here. I'm not making an opinion as to should or should not.
But... But you're also making MY point stronger. THey have a feat for it, therefore it can be done. Feats also increase skills. They also have a skill for it, it's called jump. And, since jump removes the reason you can't do it, as the feat allows you to do it anyway, then it can be done.
And, in the lose writing department, I bring in Darkness to my defense. A spell that clearly does not create light, despite how it's written and officially played. But that's a house rule, isn't it? Because how it's written it indeed does create light, as stupid as that is.
