Just throw an additional effect on it that says 'also reduces damage dealt by 5% (or 10%) for 10 seconds', and it gets a new lease of life as 'a mit tool that costs a GCD to use, so you'd want to avoid relying on it as much as possible'. You 'could' have 100% uptime, but then you throw away almost 20% of your damage GCDs to do so (not worth it)
