1. i dont see a possible reason for PIRANA to climb up to rank 3 (except for merging again...but im pretty sure it's been made obvious to everyone that the gigantic merge was what caused the war between SubV and PIRANA). Brave! and Womble has a good 5-6 mils lead on PIRANA and PIRANA is losing grounds to SubV day by day (check out your own front lines, Master B Ater, you guys have lost quite a few continents to SubV).
2. eQu probably wont get up to rank 5.
So, to sum up, the top 5 in one month from now will probably remain the same as of now (Brave! and Womble will probably keep exchining number 2, but Womble will come out on 2)
