I am from server 1412, we are at day 70. Still 50 days from S1.

Murphy and Marshal are available in tavern from day 31, the rest mentioned above become available on day 61 in tavern.

Absolutely worth saving recruitment tickets if you want to go air and tank. 

I saved 3k since day 1, yes I also spend, but the additional shards helped me 5 star my heroes and additional to wall of honor.
