No, I mean 2 seconds: with his ult up Skjold's abilities taunt enemies for one second and can he can taunt the same target twice. Like I said, you can't expect a champ to provide nonstop disruption, and none of the champions you pointed out can do so. As a matter of fact, Skjold is slightly better off in terms of continuous disruption, thanks to his passive. His longest basic ability cooldown is 12 seconds and he can easily reach the 40% CDR cap, which'd bring the cooldown to 7.2 seconds. And unless you don't want to count a second low-cost cast of an ability as the ability itself, the cooldown on his W with full CDR is 6 seconds.

I don't really see where you're trying to go. Skjold can mass taunt with his ult, just like, can slow enemies more than him (though his ability is harder to land) and can protect teammates with his barrier. Whereas has a more support-oriented kit, Skjold's is more aggressive and features more disruption. He also has slightly better cooldowns than even without factoring in his innate CDR, which means that while  would be able to heavily disrupt the enemy team in short bursts, Skjold would be able to do so more consistently.

You also seem to focus a lot on and. What about ? He has a heal, a passive armor bonus, an armor reduction ability and a stun. His ult helps his teammates slightly but provides no disruption whatsoever. And yet, he's a very capable tank. Even, who you mentioned, has only one disruptive ability, with all his other abilities focusing on support. With Skjold, if your carry's liable to get harassed you can choose to initiate with your W and dash to/silence whomever's attacking the carry. Alternatively, you could taunt everyone and have enough Rage to be operational within the next 6 seconds. Though it'd be riskier on Skjold, he'd be able to hold out much longer than most tanks, since he'd only get stronger whereas the others would have depleted their cooldowns and mana/energy.
