I don't use Maul that much when tanking, this makes Rend and Tear kind of meh. The proc on Shred lends towards cat ability as Rip causes a bleed and that is the standard cat finisher. So makes the talent more cat than bear. Maul is a rage dump not a primary ability.
As for Infected Wounds if it effects raid bosses then yes I will take it. Stuns don't work on bosses and nasty mobs so I am leaning towards this proc also not working on such mobs, thus making it more of a PvP thing. Which I would also infer from the slow effect.
Natural Shapeshifter is only taken to get Master Shapeshifter. There is no other reason. Powershifting is dead and tanks don't shift out in combat. The ability of Natural Shapeshifter should be baseline IMHO.
I will take expertise talents until I am capped. Then I will reallocate them. Until then it is 2 points well spent as respecs are cheap.
King of the Jungle gives me +15% damage for 10s every minute at the cost of -16% armor for the same 10s which equals more rage. No crushes or crits for me as a bear; so it is worth it for the added threat.
As for the t-clap reference we get a glyph to up the targets on Swipe to 4. This coupled with increased Swipe damage via Feral Instinct makes Swipe our t-clap. And t-clap is not a raid breaker for warriors. They are needed as they have been the best all around tanks. This made them the best for progression fights.
Also I think the ability you meant was
Spell Reflection . That ability makes a warrior tank needed on some fights. Not Thunder Clap.
