Considering the chances of dropping a Naga from the Ecchi in Nerva is about as much as me dropping my Lil' Red Dragon while farming the Volcano of Vulcan, yeah.
Also my math was wrong I can get Rowdy Samurai right from Rank 41 yeah I'm gonna be grinding Nerva for a while still.
@edit
nvm i'm horrible at math my team cost is too high somebody shoot me
Well, looks like I'll have to tough it out to rank 44 by replacing Horus with the Mid Fire Ninja >_>''
