You may be able to tmog gear, but that doesn't take away that the best visuals go to gear at the highest difficulty (Rated PvP gear/Mythic Gear) tiers, which incidentally also makes them the most powerful (ilvl wise).
And on your last paragraph, switching is a pain in the ass precisely because they want players to make a commitment. The abilities you're gaining from the covenants aren't meant to be "the game changer abilities", they're just supposed to be another unique identifier along with the other goodies you get from committing to the covenants. Especially since they want you to invest in the covenants.
If you're a min-maxer then you're going to min-max no matter what. You're going to take that 1% DPS increase from whatever combination gives it to you, but Blizzard will never balance the game around that mentality. In fact, as we've seen with corruption gear, they will even hotfix nerfs in to ensure players don't min-max by doing crap like using a ilvl 415 blue with tier 3 infinite stars corruption over a 465 with tier 1 IS or w/e.
And if you don't know what any of the covenant abilities do then just look at post 252 in this thread. It's very clear the Venthyr ability is defensive in nature, yet it includes soulbinds that give 5% crit. Hmm, isn't that worthless? You have a non-dps ability and a dps-focused soulbind from the same covenant. Opposite bonuses working against each other. Why? Because as said earlier, these abilities are not supposed to be some crazy core abilities. They are also one, single, ability you get to include within your plethora of class abilities. They are not "I win" buttons, but people are attempting to treat them as so.
