That makes sense.
The 4 things listed in the first screen, MVP screen, is teamwide. The second screen is personal ranking in 4 different areas. They are never the same areas and I have no idea how many different areas they look at for determining MVP. (We used to think it was most flames but that was disproven)
I understand the curiosity but I shudder at the glitch ramifications this could make.
I once suggested to PG that we be able to track our weekly medal count from week to week. (I was a level 76 and pushed myself to get 2m medals in one week. I looked at it when I was at 1.96m and a couple hours later, after many runs, it had reset and I never knew if I reached my 2m goal.) That info is not stored so I imagine the war information is not stored either.
I like the idea but I don’t think it is worth the potential glitches.
