Personally, I completely go nuts with the aoe, I find it a lot less problematic, because let's be honest here, when you have 4-5 mobs you aren't going to throw a Ruin II just so that you can weave that painflare...you are just going to spam outburst and clip painflare. AOE is simpler, in the sense you spread your dots with bane, start spamming outburst and then clip one or two ogcds between each outburst, weaving here isn't worth it unless you are under DWT or FBT.

Now...your single target rotation is a whole another story...
