Great post @Nitrus. I think you have done well in a year, especially with the 5* heroes, but also 22 maxed 4* make for quite an impressive bench!
I hope and like to think that your slightly higher spending has been some factor in landing some of those heroes, the 5* especially. As always, luck or randomness is playing its role also, no doubt.
In the weeks and months after I made my inventory post at the 1 year mark, I’ve gotten lucky with a fair number of 5*, and have been able to max a number of them (even got my first HotM - or 2 rather, got a pair of Evelyns!). I’m thinking I may do another inventory at 1.5 years, just because a lot has changed with my 5* in this time. And maybe I’ll remember to include troops that time. 
Anyway, congratulations on your progress, and may the next year be just as good!
