As you know, Ninja Proc Rate is our new layman term for rigged battle, where the (usually more inferior) opposing brigade trash your own carefully built brigade with constant near-100% proc rate chance, vs 0% proc rate chance from your own brigade.
Nothing worse than looking at your Tier A+ fams getting crushed to death by a brigade with fams that use Rush (DeNa's old favorite), Flash of Rage, Berserk, Massive Assault (OMG!), Thundercloud (yeah, that can happen!), Helfire, and you name it...
.... simply because it wasn't a fair fight, but your own brigade really got silenced and proc nothing during battle; whereas the other brigade happily trampled all over them.
Well, post your battle report here, and show to the world the worst experience you had...
