You could reforge closer around caps. Check out wowreforge.com
You should also gem for the bonus in your chest, belt and ring, it is easily worth it.
MS has a priority over CS.
Looking at the log:
Low MS count, should be able to use it much more.
You seem to be using very few Slams.
You could have used Berserker Rage one/two more times.
You didn't use Inner Rage at all, make use of that 2p bonus or it is worthless.
You CDs are not stacked at all, they seem to be used very randomly.
This is what durations of cds and procs look like:
(Managed to det DC on there twice, ignore that ^^)
As you can see they don't overlap much.
Your second golem pot isn't synced with anything, your reck isn't synced with anything.
You only used DC twice in a 5 min fight, should be three times.
Only used your 2t12 bonus 4 times in a 5 min fight.
Rotting Skull can be used 4 times in a fight of this length.
