1. There's definitely no changes in Bloodspear
2. I agree that there are strategies to counter certain heroes, but this shouldn't be an excuse to add insanely strong ones, and with this I don't mean to Ezio, but Garrick, Gizmo, Jasmine, etc...
For example, before Garrick I think it was unthinkable to see hits above 30K, but after Garrick arrives it changed that and now we can see hits of 30K, 45K, etc... from him... Gizmo, the same story, when he's going to ult you know that at least 2 or 3 your heroes will die (with few exceptions)
I understand that this is like the rock-paper-scissors game, but if 80% of the time you see the same heroes in the top teams (Garrick, Jasmine, Ethera, Gizmo, etc) is for a reason... I would like a lot if the developers made some changes to see more variety in the Arena.
