An armory link would be nice. Your rotation looks good but just as a question, on single mob (especially boss pulls) is Maul constantly up? This is a HUGE aggro generator. You may want to look at a slight change in the rotation, it may or may not make a difference. I usually Charge, FFF, Mangle, Lac x3, Mangle, Lac x2, Mangle Swipe x2, Mangle. All of these are macros with Maul attached so it goes off on every melee swing. From there on out it is Swipe in every available GCD, Mangle when up, Lac when there's ~2 seconds left on it to keep 5 stack.
Gear is not as big of a deal as people think. It may be over zealous DPS trying to get the meters to swing in their favor. When I run randoms no matter what the difference in gear I rarely have issues. Yes, when I first started tanking my Druid with about a 5k GS I had people in 6k pulling off me. I expected that. Growl, queue Maul, Mangle, queue Maul, Lac usually kept the mob on me. Typically my rotation here is Charge with FFF on my primary target then swipe spam. I do not use Maul here unless I know a DPS may pull off me. I do not have the glyph for it either. Haven't really had an issue with not using Maul and I know most people here swear that it needs to stay up at all times I just don't see the need as far as aggro is concerned.
For those who understand, no explanation is necessary; For those who do not, no explanation is possible.
