It is invalid in the fact that 85% of the people want to merge anyway. PVP players don't mind because there isn't open world PVP going on now, so it can't get worse.
Yea well most PVE players here on Dalborra are open too a merge aswell but that said the Gree event seems to be abit of an experiment by Bioware to see how PVE players and PVP players would actually get along. I personally think it went ok but there are issues with this though. For example some players aren't really happy about being able to be flagged for PVP against their wishes by simply being in a group or ops with someone who is flagged.
