I 100% accept the animation argument.
I don't accept the balance one as that's already dealt with through the Black Clover/Blue Pentagon system as well as rulesets. It can be further controlled with changes to learnsets and Egg Moves so I 100% do not buy that statement. I feel that was added to try and convince people it's for the best.
If animations were the issue, they should've been scaled back in favor of inclusion, not the other way around.
and if animations are the only issue, I don't see why they can't patch them in down the line.
