Broil 180 potency. Ruin II 80 potency. Let's assume ruin is casted on 2.5 seconds and broil is casted on 3.5 seconds (not by a long shot, but let's assume for a moment you gain an entire second from weaving).
Broil = 51 potency/second.
Ruin II = 32 potency/second.
And I'm really, really, really being generous with an entire second here. The entire point of weaving stuff is optimizing damage, if you don't, there's no point in weaving, why is it so hard to understand...
