Agreed, the current Mech pool is pretty OP, and that can be fixed without actual Nerf by adding more "bad pulls Mechs" to the pool which could also solve issues with Omega Assembly.
This happened recently with the introduction of "pack-filler" no-texter [Hearthstone Card (Arcane Servant) Not Found] : it serves no purpose other than being an indirect nerf/regulation to all Elemental card draws.
*Edit*: That said, after checking the Mechs lists, the latest trend with RoS wasn't really to introduce pack-fillers for Boom....all the Mechs introduced by this expansion are pretty good draws...

When compared with the other Hero powers from before the rotation, I think it would be wrong to nerf Boom.
It just shines in the current meta because it's one of the best - yet random- hero powers and battlecries, but it's not OP.
Frost Lich Jaina was solid, reliable infinite value in comparison.
If Boom is a problem, either HoF it earlier (then the other two Heroes may become the next targets), or introduce more Heroes for other classes?
The sudden "Rise of the Mech" revolution could hint at a premature end for the EVIL member...
