It's really hard to precisely formulate this problem when it comes down to PvP to people (staff) who actually don't play the game. For PvE it's easy, you can hit a target dummy 20k times and emulate a really fucking long tank/spank fight, draw a conclusion about procs, compare it to some ancient data when some other guy also hit a target dummy 20k times and have your evidence. On the other hand, this kind of testing doesn't work for PvP. You don't hit your target constantly, but rather you pick a new fight every other minute. I did try to get some data about all kinds of procs on target dummies before, but I got normal results because proc chances even out with their normal vaules over time when you hit continuously (For example, you get 3 fast procs and then you don't get any for 2 minutes). However, in PvP fights are short and it feels that you get a new set of few fast procs every time you engage into combat and because it doesn't last long, there is no time for it to even out with it's normal value. It usually goes like this:
Get into fight, get few procs in a short period of time > leave combat > get into new fight, get few fast procs > leave combat, etc,etc.
Because of this some people on Kronos base their gameplay on procs in PvP, instead of just feeling lucky when it happens. Like, as a warrior you can count on UTB proccing straight of the charge almost every time making it better then some other weapons with higher profile, as well as BRE which stacks up so easily. Mages running around with Imp Frost Ward cause that shit reflects literally half traps, probably same thing with frostbolts. I try to interupt heals/casts with Imp Concussive if I don't need to slow anything because it procs so much and you can actually count on a pretty good chance that it's gonna do just that, interupt/stun stuff. Half of the server is playing with the silencing sword from Scholomance cause it back to back procs and silence people for the duration of literally whole fights and I never saw someone using that weapon before Kronos (I assume because the proc was very very low?). The list is endless, there's an example for all kinds of procs.
But now, how do you compile some evidence about this and compare it to procs in PvP in 2006 I don't know. That being said and considering the complicated nature of this problem, I doubt this will ever be adressed, but it doesn't feel right when you play. When we played some premade games on PTR with R10/MC gear restriction, one of better Kronos warriors played with The Unstoppable Force instead of BRE because he base his gameplay on mace stun procs and always count on them. That's pretty ridiculous if you ask me, considering how fucking unbalanced BRE is on that gear level and also evidence in itself, but ofc it doesn't matter in this context.
