It's not to make standard stratagem more viable it is to make certain things usable. every toxic ability is cure try worthless this would at least make them usable with out something niche like aroma therapy on your team. And killing momentum. I pesos all just see the starting burn as uneceary because physical attackers are still next to entirely unusable to side of a few things. It was just a suggestion.
Every Meta invalidates something. You can't blame Inverse Battle for making Steel Types useless and Normals OP or blame BH because it ignores all but the best of the best mons and Megas around.
It's a part of the Meta. And it's best to leave the base of a Meta simple. Any irregularities can be fixed by Bans.
Worst case scenario is which the Meta is found to be very unbalanced, it will sink in usage and discussion. Simple as that.
