Which sets are worth evolving, which to trash

I am running out of bag space for different sets.

Which sets below six stars are worth evolving (and keeping in order to evolve when you get enough of them)?

Which sets are just junk and should be sold as soon as you get them.

Cheers

Armors are easy to get(except six stars)if you play for a long time.You may not have to worry about regaining the sets.Buy some heroes to keep the equipments is another option too.By the way,I think only celestial sets(Priest’s armor) are worth to evolve because you can get two shields at the same time.Others are junk and will be replaced while you have six stars armor though they are very very hard to attain.

The holy set for is worth evolving in my opinion. I wouldn’t evolve any other and save for evolving six star equipment instead.
