level 45 what should i be focusing on
so ive been playing for a bit now and I'm up to level 45 and at a point where I'm just not sure what my direction should be. i have 2 level 60's kael and deliana but I still struggle with stuff like doom tower and higher level dungeons. i feel like a lot of my equipment is kinda crap and not best suited for my champions. i just didn't know whether I should just keep grinding out food for getting more 60's or farming equipment and if so where. any tips would be greatly appreciated
