Hi 1st Spade,
Still on line !!
I have an awaken legendary heroe (Natalia) and I saw the difference. I can awake a red hereo but just have Leonardo (level 150) and Sarah (level 85) who deserve. Hope to get Asura soon.
Be careful, I am coming !!!
I have the same problem on my Iron Man account. I have Leonardo and Sarah as my two options and enough awakening stones. Both are pretty good, but I would probably try to get Smauke instead. He works a lot better for most teams, and especially with Natalia and other strong attackers. But if you are impatient, go ahead and awaken any of them. Both of them are pretty decent and performs well when awakened. I have not have any of them awakened myself, so I can't say too much about their performance. Leonardo awakened might be the best defense against Hanzo, which of course is very important. Sarah has a very good attack and her silence skill is very good. I can't even make up my mind when it come to which one I would awaken. For a super performance team I would probably pick Leonardo for his defensive skills vs. Hanzo. For a more casual team I would probably pick Sarah for her good offensive performance.
Asura is also a better option than the Epic heroes, as you mention. But I still think Smauke is the best option for you.
I'm waiting for you to kick some butt
