Its quite funny. When the game started they were obviously trying to differentiate it from Tribes but yet keep it similiar. They ran into some pitfalls and obviously a large number of Tribes players who werent too keen on some of the attributes of the game. Since then its becoming more Tribes like which is great. No one even knew they would add what is basically a light class (outrider) and also they are adding what is basically the heavy (sentinel). But its pretty much a skeleton of a game right now. Hardly any content. There are also questionable issues with the whole browser thing.
I still hope someday, some dev company worthy will actually make a good successor. Not Tribes like but Tribes.
