Resource investment should come into play. I’m not arguing against that. But resource investment should come from which character(s) you farmed, geared, and zetaed.
If I have 20 G12 characters consisting of Luminara, CUP, Ugnaught, etc., and you have 20 G12’s consisting of Revan, CLS, JTR, etc., you deserve to win. That’s fair. What’s not fair is a 20 character and 20 zeta difference, all because meaningless GP is the same. That’s lazy programming with today’s technology.
