Hi,
If you somehow get killed during the Starboy encounter, if you feel like randomly destroying the orbs during Botanist fight, if you don't know how to break the chain during Gul'dan(or come to assist), if you can't eat cakes during Trilliax, if you don't know what the bubbles are for during Elisande, if you rather DPS Krosus instead of soaking imps;
Most importantly - if you ignore the mechanics, just to get better logs(as the casual you are) - please stop doing PuGs. This is getting out of control. Its not fun and waste of time.
Just play normal until they nerf HC.
