[2021] What's your main defender and attacker and why?

I swap defenders around a lot, but recently I've been hard stuck on playing Aruni. I absolutely love the MK and having the utility denial/being able to slow down rushes/ audio cues of the Surya gates.

For Attack, I usually find myself playing Kali or Mav. I've been playing sniper-type characters since childhood, so the draw to Kali is immediate. Plus, knocking out spawn-peeks and nailing quick scopes, or even just getting a long-distance kill is a super satisfying feeling to me.
For Mav, it's really just because i love getting sneaky kills. or being able to pop up in unexpected places is a pseudo-stealthy manner.
