Oda is very good early-game but imo with the way professionalism works, most of those leader pip ideas are not as valuable as you'd think, most generals are going to roll very high pips regardless nowadays. Only the siege one is truly precious (also note it's Leader Siege, not Land Leader Siege, gotta get those blockades

)
