The best use i've found is to if you have 15+ stacks when RoR procs use it straight away, then use it again (hopefully you've got 10 stacks again) right at the end, that gives you 25 seconds of the RoR bonus. You overlap your two uses of TeB but i still see a bigger use of it this way.

You don't have the haste/crit for that time, but you have to know you lose your crit rating not all your crit, so full buffed you should still be around 30% even when it procs, and for the haste you just plan your Energizing brew at the right time so you aren't energy starved during that period. But the main problem is having it proc at the right time ofc because it is quite rare (in my situation anyway) that you have enough stacks when it procs for it to really be viable (of using it twice).
