The other tabs - battle wins, value (price not actual value), and ally boards all have a factor towards overall rank (labeled Strongest on PC for some odd reason.) Which is why "strongest" isn't really the actual strongest. You can manipulate the price of an account without changing anything else and it WILL change the overall rank the next day when it updates.
Reeb back when Chongo was #1 on strongest LB he was, at least, -3 on all the others. That means that the strongest LB is another animal entirely... As already stated by Altitude, those PCs don't have an "overall" LB.
To reach #1 cost more than $320 a day. It's $320 x multiple accounts daily. It's possible to active lb status without spending the $$$, but you would need more Alts than Val hitting 24/7. Lol
It is most strongly influenced by spy action wins. I had a debate on this with IGCB a long time ago while I was in semi-activity. Chongo retained number 1 on overall despite being second or lower in all other categories. He was held in overall because of spy wins.
I would find joy in a daily "happy hour" where players prepare themselves for 3x battle list hits, and EB players groan as they prepare for their daily beating. It would just throw all walks of players into pvp gameplay so they don't just play for the EB's, get bored, and leave.
