Just an idea, not sure if it has been suggested or not before. (I did find this "Choose Your Loot" box but it’s not quite what I was thinking)
Basically, at the end of filling a chest, be it war chest, titan chest, monster chest etc you get a choice of two loot packs.
You can see what is in each pack, they may not have the same amount of items but you can decide which pack is better for you.
E.g you fill a titan chest, you click to open it then you see something like this =
Crystal shard, crypt mushroom, training manual, tall boots, string, poison darts, epic troop token, 10 gems, 2 cleric emblems
Grimore dust, hardwood lumber, miracle scroll, warm cape, farsight telescope, 20 gems, 1 fighter emblem
If you need a telescope, you’d go for pack two, if you need darts then it’s pack 1.
It would slightly take away some of the complete randomness of the loot in a way that would be helpful. Sometimes you may not find anything you need in either pack, there would be packs with no ascention items as happens now, but I’d rather be able to choose the better loot for me either way.
