No, it's waaaaaaay different from breaking BBs. At least with a BB you can warp away from the MVP and there are still mobs to kill. When someone hylos it just ruins it for everyone, worse than when a champ mobs, because most of the time a hylo turns a monster into like a picky or poring or something lame (having High Wizard Katheryn there is pretty much the same as having an MVP there, tho, you just warp away and sacrifice your mob to the MVP Gods and find a new one). Then someone has to go around and kill all the stupid monsters so the good ones respawn.
