Forum:Serin Stats

Hey, I have two serin units , both are anima and level 59. Yet one serin has both a higher hp and rec then the other, I have caught a serin in 4* form but I'm not 100% if that is that serin or if that capture would even apply to anything at all whether the stats be lower or higher. I'm sorry it's just been bothering me like an ocd this new discovery for me really changes a lot of my idea for units for me, please help.
