I know this has come up before, but I couldn’t find a post with the most recently released characters by release date, so I created one using the info at news.marvel.com. All dates are taken from the announcement. For Peggy Carter and Thanos,the date may be off by a few days, since those posts did not have an exact release date in the same format at the other (they said that the character would be available in an event on the given date, but may have been available before that - e.g. Peggy was available in the event before the one listed below)
Thanks for posting this - I was wondering how long it’s been since certain characters were released. It also shows that bonus heroes have really helped me to champ 3* - I champed both Thanos and Strange late last month. I just champed Hawkeye yesterday. That’s 3+ months to champ Thanos and Strange, and about 5 weeks to champ Hawkeye (he was set as my sole bonus hero after champing the other two.)
You’ll get no argument from me that Bonus Heroes has been pretty awesome at the 3* level. I champed Hawkguy within the past week as well, pretty close to the one month mark.
But my experience getting a 4* BH has been pretty abysmal. They need to drop more frequently or have some kind of steak buster feature implemented.
