We do support it.
Regarding the legendary, does the simulated dps go down substantially when you make the proposed change? If so, one thing to keep in mind is that legendary items are integral to the setup for any gearing strategy you run. You might need to lock in the legendary items you used to create the strategy before you run bib. Our new default gearing strategies we are working on can help with this, but they are still being worked on and will be made for 7.2.5.
For the trinket, convergence of fates can be very strong depending on the fight length. Your gearing strategy was probably made with a fight length where you can get an extra use of meta, making it very powerful. If you don't want to use it, you can change the fight length or increase the fight length variance on your sims.
