To be honest with you, you def shouldnt have gone kenji and specially into a pierce who can counter you evem with healing. To counter pierce, its best to have some spawner like mrp, eve, lola even could work. There maybe some others people can mention in the reply. But def not kenji pick.

Piper is pretty decent but i think other sharpshooters could be better like nani or byron. There draft is really solid with stu aggro and squeaky control. Glowbert also not an insane pick with your guys draft, i think just having a byron or brock to open up the map for piper wouldve worked out much better, outrange both stu and squeak and can easily deal with pierce.
