''They have extensive research data that concluded such a reset day is the best for majority of players'' I guess you can't read, or better said you don't have any hint of reading comprehension.I'm basing my opinion on the fact a multi bilion dollar gaming company knows the playerbase better than a couple of randoms like you, OP and me, hence the strong recommendation to follow their raid reset days.Hell, even tuesday morning is more than fine, but not the silly mid weekend suggestions that have been tossed around, or monday morning with no chance for reruns when most guilds raid sunday.
Most guilds raid sunday and monday on retail btw.
