Vengeance or Concentrate Which is better to add? Vengeance or Concentrate? I currrently have 0 pts in both. Im leaning towards Concentrate for that stackable wa boost. These are the skills i already have in case you're wondering why Im debating those 2 skills: SE max, Hurricane max, BE 29, Markmanship max, Mw 19, DB 1, Phoenix 1 Thanks in advance ;]
