Your druid can EASILY reach the 13k haste breakpoint which is a much better. He also has too much spirit, IMO. He can go up in spirit with the weights im going to give if he's not comfortable, but generally you don't need that much. Yea, hes going to lose a ton of int, but the haste is worth it.

Next with logs, I can't help you very well with World of Logs. It's not as informative as Warcraft Logs where I can see the exact spell usage. WoL is not up to date any more and I wont be surprised if its completely dropped next expansion. If you click the link in my signature for analyzing a druid you can see the special graphs I can see while using WCL. All I can do it give some general comments on what I see with WoL.
Harmony uptime: 100% good.
Lifebloom uptime: 99% good.
Swiftmend: 14 out of 20. This can be a little bit better, but the swiftmend usage is ok. The problem could be what he is using Soul of the Forest on (which is easer for me to see on Warcraft Logs.
Wild Growth: looks like 21, kind of a guess with WoL, and I again can only guess that he missed 4 or 5 SotF on WG usage. It's important to use SotF on WG or tranq for the most part especially on a fight like Iron Jugg, theres just a lot of random damage that Wild Growth will just catch.
I can't see if he used the clearcasting procs correctly.
I can't see if he used mushroom correctly.
I cant see what spells he used during his meta gem proc.
He used 3 Nature's vigil, so thats good.
Only 1 tranq, but the length of the fight probably means there was only one siege phase.
1 nature's swiftness, I personally think this spell is amazing. It can top ANYONE off and its one of the only forms of single target burst healing we have.
Ironbark 2 - this is good, could be used more to help with tanks, but if they aren't dying then w/e
Overall the log doesn't look TERRIBLE. Though his low healing output compared to the priest in a 10 man can be remedied by going to 13k haste.
Thok is more of the same.. Could be just a little bit better on swiftmend and maybe use the SotF better. Seems like hes using Bloom too much, its not that great when hes at max casting speed, better to let effo carry it through and use it to catch back up if you're behind.
If you want a better analysis you need to come back with Warcraft logs.
