Ony buff reset needs to be fixed

I play on skerem and we have the assholes of onslaught on our server. Ony is on a 6 hour reset so you have make sure you are on at certain times to get the buff.Well onslaught are super try hard and like to be asshole to people cause this is the internet and that's what people do. So they reset the timer for when they want to raid and screw up the timers so people can't get the buff. So we tried to reset it today at 630 so everyone who was expecting to get it could do that and then if onslaught wants to get it later they can just reset again.They are now camping our alliance priest so that we can't reset it and get the buff. Pretty dick move to not let people do the same thing you did hours earlier.TLDR: Onslaught reset which messed up the timer. We tried to reset to get the buff back and they griefed it. Blizz needs to fix the reset so this doesn't happen.
