Mastery and Versatility are still necessary to have some base degree of mitigation and Crit will help your healer keep you up in extremely high damage situations.
I've been doing +4 and +5 this week and I haven't felt like the timer is particularly strict. If all you're going for is +1 upgrade you can just give yourself a breather every 3-4 pulls to let some of your brews/BoB recharge and still make the timer. Every tank with CD based mitigation suffers from this problem somewhat and the solution is either to go slower or manage your cooldowns better. Exploding Keg can usually save you a charge of ISB, Leg Sweep can save you another, plus CC from the rest of your party. If it really comes down to it, just roll away and kite while you wait for charges.
