I have updated my guide to include all 5* that were added when v44 went live. EDIT: Also added EPIC and RARE heroes that were added as well to training levels 8 and 5, respectively.
Unless you have 5x Classic 5* costumes, AND 5x HotM, I strongly recommend running HA10 5* retraining for 52x retrainings ( 365+ days )
On average, this will give you a combination of 5 new options ( Classic 5* costumes, Limited availability 5* heroes, Limited availability 5* costumes ) for roughly the same cost as trading 10x 5* heroes for 1x 5* hero ( 400+ days )
Yes, when retraining epic troops in HA 9 you will get back a different troop than the one you put in. It can be a different color or same color but different type.
I’m missing some basic 4* session 1 costumes, like Melendor who is a most… With the new calendar schedule, we will have less oportunitis to get them. Every 2 months (!), right?
Please add 4 session 1 costumes into Hero Academy Level 8!*
