I was thinking that it could be beneficial if there were a score reported after a PvP battle that would let you know how many points you would have gotten had that battle been in GW. Something along the lines of “If this had been a GW battle vs. the Paragon, you would have received XXXX points.”
It could help with fine tuning teams that are maybe a little slower or tend to lose a troop, or any number of things that could affect your score.
Obviously the formula is already in the game, I don’t know how hard it would be to port over to PvP. Or even if anyone else would find the information useful.
