Why would the crit thing make any difference? Let's say a crit deals 50% extra damage (i don't know the number), and every tick of doton crits, it will deal a total potency of 8 * 45 * 1.5 = 540. If you use raiton instead and it crits, you deal 400 * 1.5 = 600 potency damage. Or do dot ticks get more extra damage from crits than normal skills?
