Excuse me, but what is your question? What kind of help do you need?
i dont know what the question is but i see a “problem”
you have A LOT of partials, when you start working on a hero, finish it before you start another project.
a fully maxed 3* is stronger than a partial 4*
a fully maxed 4* is stronger than a partial 5*
3* heroes are the fastest to max, then 4* then 5*
pick a rainbow team (one hero of each color) and max it before you start with other heroes
most 5* heroes will sit at 3/70 till you get the mats you need to break that last lvl, so a fully maxed 4* might be stronger
same color feeding ensures that you lvl faster, yellow feeders go into yellow heroes, blue into blue, red into red, purple into purple and green into green
true you can dump all your feeders into the hero you want, but they dont all give you the same points.
It is best to either finish heroes before going to the next one or at least take them to a stopping place (such as a 5* to 3-70).
Same color feed: yellow feeders to yellow heroes, blue feeders to blue heroes etc. They level quicker that way and you get a better chance of the special leveling.
Focus on getting a good rainbow team completed.
And have fun!
