Normally I expect posts by me to get rated down, however recently posts I have made that are nothing but helpful and are not flaming or have any sort of negative attitude.
Recently I had a post in the summoner forum where I described the gear stats you received from level sync in a promy and sacrarium level cap area. My promy area was rated to good and the sacrarium was rated to default.
Other places I have noticed where I said something completely agreeing with someone and adding to what they said gets rated down too. Any time I debate with someone I expect a rate war, but when I am simply posting helpful information it just gets ridiculous.
