I would rather put up builds that give stats than drop rates. I'll eventually get whatever drop i want lol.
Sure that's your choice, but other people would like a wider variety of choices. Just because ebs drop items/equipments randomly doesnt mean you will get it eventually, nor does it mean your chances increase depending on the amount of ebs you complete. Each ebs is independent from the previous and next to follow and each other, other than the way you unlock them lol
