Hey! Wanted to throw us out there. We are a group of older people looking to get AoTC. Casual guild regularly running M+ on non raid nights whether it be alts or mains. I know you said your times were 8-10pm EST, was not sure if you were flexible at all. We raid Wed & Sun 8pm CST (9pm EST) and usually go for about 2 hours. We are currently looking for a healer!
