I make spreadsheets to track my map and map-type win percentages, and I thought I'd drop them here!  There's also a sheet to track bans that will automatically update the top bans of the season for you!  

To use, just make a copy, one each for DPS, tank, or support as needed.

I gave this season's sheet Vendetta colors since she's the star of the new season. ^^

Here's the link!
