The whole point of their starting unit is to feed kills to the enemy team and if you fail to maintain your ability to spawn as a Legionary, Archer Militia, or Palatine Guard, you're effectively removed from the game. In the times that I do play MP, I often make it a moral obligation to fight against Empire.
Regardless of how you feel about the game's balance though, something definitely is wrong with it since players have been driven away from playing it even during the competitor's Epic Games Store exclusivity period. The only people really left playing it as of currently are often just the folks who only care about flexing how loyal they are to Steam that they'd rather play a bad game on Steam than to give any amount of money to Epic Games.
Hence why I predict that the supposed 1.3 update's key takeaway (if not the only change) is a termination of service.
