I'd prefer if all the modes were revitalized again, not just Seal Rock. In fact, Seize is easily my least favorite of all the PVP modes but I'd gladly do a few matches of it every week if there were incentive to do so. I don't like seeing PVP content dumpstered as soon as the next new shiny comes along, even if I don't care for it personally. Variety breeds adaptation, which generally makes for better players overall, IMO.
