Pie vs. Cake area takeovers

Wouldn't it be worth more to grind during the time it'd take to fight to get the 10% bonus?

If it were 200% or 400% I could see it being contested and heavily worth it, but for something that tiny seems worth more effort than gain.

the battle lasts literally no more than 15 seconds. i lag when i go in so i just hold down hurricane button and when i unlag the battles over. this is one of the stupidest events yet. cake battles that were lag fests and took like 10min were much funner
