I'm okay with current top 5 aside from Churchill I.
Churchill Crocodile in 1st. I have her but I don't use her.
I personally would prefer IS-2, TOG II or FV214 Conqueror. I use all 3 as my heavy tanks and FV was my from my first free monthly 5star. Was disappointed to see that I drew a 5star without story.
Was surprised at Churchill I on 2nd place... Rather she not win. Would feel like a waste of a poll being a 3star.
