this game does not need a complex system of rewards/achievements, the current cbill system is pretty good imo (you don't need kills to earn money, for one, i LOVE that), the problem is mainly with rounds too easily becoming one-sided, particularly the maps without all the assets available
i just got off a horrendous round of Marshes where i switched to the other team a few minutes in to balance them out, all the vets on my former team said "Hey thanks for switching, derp" and proceeded to roflstomp me for the next 45mins; i was keeping a consistently high score and was at the forefront of all the major pushes that ended up being satisfying but all too brief point caps for my team, not just because my team had a lot of quiet types but we were all pretty much inevitably stuck in subpar assets, and it's not like i could beg them for money just so i could buy an MKII and faceroll what few meds/heavies i could find, we were all broke and it just didn't make any sense to me to try and be superman in a light asset for a couple deaths by myself just to save up money, wouldn't have helped my team one bit
i really felt like if i could get some ASF in the air i could've maybe at least picked off lighter guys around the map a lot easier and told my teammates where to cap, etc; thunder rift is a good exception to what im saying though, i hated that map at first but its grown on me a lot
point is, there needs to be something that can give the team with the lesser momentum a chance to build some back up, it needs to be fairly obvious to new players but it can't be too helpful nor can the winning team be totally excluded from its benefits; that, or the servers just need some better admin presence to mix the teams up when need be, i cant even remember the last round i played with an admin around
im not trying to be confrontational here, but i've been playing a lot of lopsided rounds lately and it's starting to get frustrating
