Three thousand years is a pretty long time, and it didn't sound like they broke out so much as an outside influence broke them out (intentionally or otherwise).

But regardless, I don't think seals take power into account. I mean, the entire Demon Clan couldn't break out of the Goddesses one (although Meliodas did note it was extraordinarily powerful) so Meliodas or Escanor just breaking out through sheer force would leave a bad taste in my mouth.

Of course, Meliodas broke out of the Goddess Amber, but that was specifically noted not be able to hold a demon of his caliber. I'd image the goddesses actually did have ones that could seal him or the Ten Commandments potentially permanently.

Oh, and as for the big guy, I've been assuming he has two heads; because his his dark shilloute when they were freed had one. I'm not sure about your idea. We've seen a troll, they don't have four arms and I don't image they'd normally be strong enough to warrant being in the Ten Commandments. Intersting idea, though.
