i’m ultimately aiming for a crit build of around 33%, and probably to drop dots almost all together. if you look at the ruin talent for warlock it means a shadowbolt talent that did 2k damage can do 4k damage critical 2k extra damage and with a high crit build at 33% you can equvalently say you will have increased you average shadow bolt by 666dmg through crit(ie 33% of the time you get double damage so extra 2k from ruin divided by 33% of time equals 666 extra damage on average percast time of 2.5 secs , then 666 extra damage/ 2.5 cast time = 266.4 extra dps. This doesnt seem to big but when you add talents and items that also activate of critical stikes this can escalate further.
