I wish that you could win coins for epic warriors on the world map battles.
I had 2 epic coins that I used,
Whit one I gott the grim, but he’s only a third as strong as it says he shuld be.
For example life-force is only about 600 on mine and the one in the generator is 1500
You need to level yours up. At maximum, he will show that much higher level. 
Grimm is a good Hero; I love mine. Here he is at last ascension, lvl 54:
Tank for info,
But I which they could give us more badass fighters

Grimm is pretty badass for a 4* hero, once you get him fully ascended and leveled. I use him daily on 3716-point, 2500-trophy team and expect that I’ll use him often even after I replace him with Magni in my main team. There are many, many weaker heroes that the summons could have pulled.
The real badass heroes are 5*. You have a chance to summon one in the same way you got Grimm. Odds are something like 2-3%,though, and then you’ll need a lot of rare items to ascend them.
Enjoy Grimm!
