@Noble_Weasel is right. Stop summoning! You have enough heroes to keep you busy for a year already.
- Build 2 or 3 3* teams and get used to using them. Learn how the specials work together and how to time and target them. Then do the same thing with 4* teams. Then, and only then, start working on 5* heroes.
- Get into a good, active teaching alliance as soon as you can. Not only will that open up opportunities for war and titan loot, it will also give you access to people who can help you get the most out of your heroes.
Here’s a link to a thread with lots of teaching alliances:
