Don't see it happening but support. Either way I got my own system to keep track as I'm much sure most do. Nonetheless again SUPPORT
I just don't see why you can't keep track yourself .. Aside from that of all things the game the devs could be working on this is one of the least important and or useful
The idea was that it was private to each user and would only provide aggregate comparisons so nothing too specific. Also if you have time to look back thru eb's and keep track of ally sales, pot purchases, war mith investment, war wins/losses then more power to you. In terms of dev effort this is really easy as all this info is stored in the database. Just write the query and with the new creative team design a nice page to view it in.
I really like the idea full SUPPORT, but id rather they use all their time to fix the EE wars before ANYTHING else
