For now… just to get my current team of 4* heros maxed. (Just managed to ascend my Sonya… woohoo - now have 2 on final ascend, and just 3 to go (or 4 counting my spare green 4*).
I don’t have any great aspirations to build a 5* team as it will take too long and I’m not prepared to spend the real world money to do so. Any that may come along is just a bonus.
Once I have my maxed 4* team I’ll see where that takes me on the raid ladder, until the frustration gets to me (which won’t take long), and I guess at that point there won’t be much left, so will probably move on. (Guess I’ll finish the map at some point).
Not really into the higher level Titan fights - the reward isn’t worth the input - tend to need to chew through battle items to score competitively. May be more worthwhile with a stronger team, so may dip in again if all fully maxed.
