@@MrMacncheese1 Yes, Higher tier is always best if we can exclude Power/Point Exchange in many scenario. Siege vs Siege is mostly a Coiners game those who can compete in Buff vs Buff scenario otherwise as such its not mandate to use only T11 or t12, Same goes for Big siege. you will know while hitting keep on the basis of your buff/ Debuff and your opponent Buff/debuff and quantity of siege, which layer should be more to give you the best outcome.
