Tbh, on the log where you're at 902 ilevel, the ilevel perf is at 80% for goroth (aka you're above 80% of the logs for your ilevel) which is pretty good, given you have no T20 and you run sephuz/aggramar, which is, let's face it, pretty nasty.
You died on Harjatan, so not much to see there, even though you really should go FoB on Harjatan. Rend falls quickly out of contention as soon as there are 3+ targets.
Also, as soon as you can cleave in a fight (aka any fight but maiden and goroth), you should pick sweeping strikes over dauntless.
