if you're tank yii you'll be in the fight much longer, which means you're gonna be getting hit with a lot of cc's

either swapping out the AS boots for merc. treads or swapping your maw for the merc. scimitar would be wise, as you'll be too easily controlled to do sustained damage as a tank. the scimitar's active would not only help you with a cc that would disrupt your highlander, but grant you an extra boost to catch back up to anyone

but the boots are prob a better bet, as the shield/passive from maw is strong, as you mentioned.
