Simple advice if you are f2p : well, you will always get rekt by heavy spender no matter what, just get over it.
For p2p : well, they are no different than f2p...if only they buy the monthly pack or Jounin medal.
For p2w/heavy spender : You are a nightmare in the server, just spam all the "yes" *on on those event that required to spend ingot and grab the reward...for ninja part, as you are a spender, just buy whatever you want and exchange all the medium refine, charm, and rune pack.
