The cavalry really be stomping people once a team gets to spam it.Please make sure to do massive balancing improvements before realizing it. After playing a few matches yesterday I noticed that there are a lot of flaws with the class system added into a battle mode. I'm not going to refer to the current gold gain and costs of the classes because NIN3 already mentioned that, that will be taken care of.
But with the current system on how this is supposed to work the "snowballing" is way to extreme. As soon as you get stomped one round (if rounds are close the balancing could be a little better) the set is practically over because the light classes are no match to the heavy classes. To prevent every set from being 3-0 or 3-1 you could try to add some kind of loss bonus depending on how many rounds you lose in a row. Meaning the more rounds you lose in a row, the more gold you get so you at least have a slight chance of making a comeback.
Also, it seems like the gold gain is mostly around your own performance and that determines if you have enough gold to buy a proper class. But for competitive play I see a few issues in that. If for example I'm playing cav and holding of the enemy archer the whole round I wouldn't be making any kills because I'm busy holding off the archer for the team (still doing my part for the team). And then if we end up losing the round, this would lead to me not having enough gold to buy a cav class again and one of the infantries would have to step in as cav. I'm just not so sure if this is really the right thing for a competitive atmosphere as you get rewarded for playing selfish (grabbing kills) and punished for doing things for the team (bumping, holding off archers etc.) I guess this would also happen to me if we end up winning the round and I wouldn't be able to afford a heavy cav depending on how exactly the gold gain would be working. Sorry I'm not very good at explaining it but I guess you know where I'm coming from. Currently I don't really have many ideas to fix these type of issues but perhaps someone else has some ideas.
I personally would much rather see a custom equipment system similar to the one in warband. It might seem like a lot of work at the start but once you got everything set up with it, it could be much easier to balance the game with it.
Also, i think most people tend to not use their view character button to look around them. I feel like this is a good time to bring up they should fix the camera motion and how sickening it is when used.
