I have many questions now ...
I'm not sure why you would six star sister militant, but whats done is done. You have dark elhain, scyl, lord legonary so you have been playing for over six months>? I feel like you should have many more epics at this point, make sure you only open shards during a 2x going foward.
Looking at the stats on your athel I would assume other champs are geared similary? You speed is way way too slow, you have almost no crit rate , and zero accuracy from gear.
You only have 2 60s so you really need to make a team from the ground up. You have a decent amount of food so I would suggest scyl, and probably leveling warmaiden so you at least have a defense down, then ninja or coffin smasher for attack down.
I would stop worrying about DT at all and start getting a solid dungeon team together, farm dragon for speed/lifesteal gear. As well as start doing clan boss.....
