it is natural that they be considered in a similar manner...
and the rule was probably implemented so that centigors would have +1S on the charge...

otherwise the trample rule (another rule BCs have escaped) would be pretty pointless...
Actually a cavalry spear is reliant on momentum to be effective, a bit like trying to manually propel a balitsa bolt by running really fast with it.
A Great Weapon is reliant on the weight of the head of the weapon to slice through an opponent's armor. However, the reduced effectiveness of the weapon from horse back comes from the fact that the horse's head is in the way of the most efficient swinging arch as well as most people not being quite that stable while mounted to deal with the momentum of the swing. A Bull Centaur has no such problem as their upper, humanoid, torso begins where the head of the steed would be, and the fact that they are fully connected to their four legs they are more stable than someone on horse back.
Just a correction.
just conjecture you mean...
its certainly no where in the BRB...
it certainly doesnt explain the disc of tzeench... or chariots at all...
is Chaos lord on dragon penalized twice? one for each head?...
if the chimera returns will the GW give a negative S value?... swiss cheese...
"restricted movement" (p.56)... is cited as the reasoning... whatever that means...
why were heads of ridden creatures not a problem in 6th ed?
did 7th edition change the physics of the universe?
no it didn't... it changed the game balance of cav units...
there is no reason to asume that BCs should be exempt from a game balance issue...
It was a correction on the comment that both weapons use weight, and hence are used the same way or have the same negatives. Not a comment on the rules, but of the reasoning.
A person fighting from horse back would be less effective than a person on foot with a greatweapon, and I agree with the change in rules between mounted and unmounted, though not necessarily on how the Bull Centaurs would have such difficulty in using the weapon.
As the Bull Centaurs now count as cavalry, it is generally accepted that they get the +1 armour save for being "mounted". So a shield & HA will give you +3 save vs missles all the time and in HTH if you only use a hand weapon.
Woah, woah, woah, woah. . .woah. . .
When did they become counted as calvalry. I haven't heard about this! Could someone explain this lil' tidbit to me. Thanks.
One time I charged my BCs into my friend's dwarf organ gun, but lucklily he rolled a misfire, we decided a squirrel got stuck in one of the barrels. His crew still doesn't check for squirrels, much to my relief.
