It is very slow compared to DOTA2, that's for sure. But is that too slow?
I am actually not convinced that it is for the type of game they are trying to create. For competitive players maybe it will be too slow. But this game is NOT a standard MOBA. They are actually redefining MOBA with it...and I'm not saying that they are making DOTA 2 or LoL irrelevant with it, just that they are expanding the definition of DOTA. But I actually think they are carving out a VERY nice little niche for themselves, that could turn into something.
I just played some more...and the more and more I play this, the more I LOVE it. Geez. I was luke warm at first, but then I hired a pirate to siege the enemy base with a ghost ship after I broke open a golden chest. THIS is the type of outside the box thinking I want to see in the MOBA genre.
