Love the idea. Looks like it going to take time, to test out and reconfigure if need be. Which I believe it will.
It entices people to pay more attention to MA, maybe upgrade it, which brings in some more Income to Inno. Always a + in my opinion
It also makes people think to compete more in Tournaments to fetch loads of Relics and Spells!
All in all, I love it, wait... I said that already
e - I will add. I had mentioned in another thread about, somehow getting rid of Event Buildings we don't want, which could maybe give a "blueprint"
@SoggyShorts also commented in that thread.
I wonder if they took that idea and ran with it for this MA...
If so, I had stated long ago, if someones idea is taken by Inno in any shape or form, then added into the game, there should be some kind of "prize" even just a; Hey Thanks for your idea!
It's a glorious feeling to be a part of something and get a lil praise for it by Devs.
But that's just me being kind, do as you will
