Thoughts and Suggestions for Battleground Blitz

This is the only way I was able to know my team before I downloaded an addon, lol.
I still think it should just use red / blue and not a faction for clarity.

I also still spend too much time on queue compared to playing, why exactly do blitz matches need to be sped up so much? Normal BGs aren’t long or anything.
What is the purpose of speeding them up? Do I need to make sure my match will finish before my train trip ends? Am I playing WoW mobile in Tokyo on my way to and from work?
