Best potential team mode composition?

This is mostly based off of my thoughts:

Aqua: Can slow down anyone, leaving pushes in vain, and can kill quick.

Alex: Actives good for covering spawn, although it can quickly be destroyed by explosive.

DDOTY: Bad mellee attack, but excellent active ability and good tank, Renner may be a good substitute as he also has took kill potential with his primary.

SLEEPGROUND: Really just for healing. If anyone has any suggestions, feel free to reply! Just be respectful of other opinions and be nice.

Sorry I dont agree.

I'm interested as to why. Please tell me, I'm curious about your opinion.
