Here is my personal opinion as an Elemental Shaman:
1 - He's under cap - he should be with 15% hit
a) he missed 5 flameshocks in elegon fight, what did he hit 22 LvB with no Crit
b) Same in the Feng fight - 2 Flameshocks; 2 EB; 1 LB and 2 LvB missed - and 5 LvB with no Crit
2 - He should buy "Relic of Yu'lon" and replace the "Thousand-Year Pickled Egg" - I know it's off spec, but weapons and trinkets can really affect dps
3 - He should use twice per fight "Stormlash totem"
obs: Searing totem or FET should always be up, I can’t say with his log if he's doing it but he should
Sorry for my bad English...
