Re: BOTD or Grief
Depends whether you are pvm or pvp. The worst grief will still outdamage a perfect eBotdZ, and for pvp it's grief hands-down. Botd shines more at pvm, with high leech and indestructibility but lower damage.
For pvp it's grief
For pvm it boils down to whether you like faster damage and don't mind repairing or you like high leech and no repairs ;D
