This is why I avoid trinity content. I hate being chained to a tank and healer and putting up with prima donna bullshit. It's why I love the Deep Dungeon, cos I go in relying only on myself to finish. Everyone else is just there to either help or die and slow me down, mostly the former. So if you're after weekly Tomestones, consider doing POTD as an alternative. That or try Frontlines Shatter spam, BRD is great in there.
