Switch gear depending on ST or AoE

[Yonaz]

Something occured to me, now when I started stacking up on trinkets. I have 2 x Devilsaur Shock-Baton (840 and 845) and Unstable Horrorslime 870 in bags. Aran's Relaxing Ruby 860 and Wriggling Sinew 865 equipped.

Mastery increses our AoE and versatility general damage. Would it be a crazy idea to have Crit+Vers gear for boss fights, and Crit+Mast gear for trash and AoE? Or is versatility still too bad to be a "main"-stat?

I have being doing this when starting raiding / mythic+, especially with the very-easy-to-use Sets ingame functionality.

ST set includes Sinew, Crit heavy / haste (which sims higher than mastery for me in 1 target), etc.
AE set includes horrorslime, more mastery etc.
Particular trick in M+ is to switch for ST one pull before a boss, so the Sinew 30sec cd (when equiping the item) is gone on pull.
Versality sims lower for both scenarios in my case.
