So I was doing a 450 gem roll and I got professer ribbit. She was born with a 5/8 heavy blow. Is she a good hero?
If you are a new player, she's definitely better than a lot of the older heroes, and way better than the shard heroes.
However, she's definitely not in the Top 10 or even Top 15 list of heroes.
I would say it all depend on which heroes already you have.
If you have Rockno, Sasq, than she is not that good to deal with.
If you don't have good tanks, she will have some worth to you, till you find better ones.
But overall it is like HB said, not top 15 on heroes list (at least until someone find her good spot).
The only benefit you will get from froggy is when your heroes and might are levelled enough to use destiny.
You will need froggy for one area to build up your other heroes
