as it stands, knights are OP to the point of most future make-ups being at least 50% knights (with 6 current 2-1 classes, thems not be good odds, yo)
you make all these "throughout the game" defences for your stance, but we're playing a completely new meta. if knights can spam el cheapo pots at much higher efficiency than other classes, while dealing huge amounts of damage, all while being mounted -- then i don't see a problem with other classes mounting up when they can't even attack
some things can be assumed to be bad for WoE overall, while others may be good. testing & discussion will be the only way to come to a clear decision on matters
it doesn't sound like you even understand what game you're playing yet
New hat idea! -40% damage from Bowling Bash and +30% damage to Knights.
