Infantry should be allowed an instant dodge action when they could manually just dodge. If it was the case maybe cav could get a boxing horse animation that when they block at the moment they are hit by a weapon the horse rears and boxes the perpetrator to death and is immune to further onslaught for 5 seconds
but in all seriousness, if infantry are aware they can dodge out the way manually (Just Dont! cause I am not gonna reply 2h's) they dont need a quick reflex save as well.
the 'self bump' was an idea that was accidently implemented into final patch, it was a 'possible' nerf to cav and while I feel it was unecessary it also did a pretty good job of not upsetting too many cav while making footmen feel satisfied (the greedy bastards). The bump I admit was not great for 1h cav, especially due to the fact that they now had no counter to turtlers, but then again cavalry is a support class, not a class designed to beat opponents 1 on 1 all the time, maybe shielders are to 1h cav like the high athletics kiting archers are to the slow infantry str build. However this once again would unbalance lancers and 1h's due to 1h's not being able to take down nearly as many potential opponents. Its all in the balance.
But no I dont agree with a 'press x to dodge' scenario.
