Were currently in the process of a complete rebalancing of all the factions in the game. We felt that capital ships were dominating the battle-space and that just wasn't Star Trek. Were trying to make all ships relevant even in the late game so even a few Cruisers can take out a Capital ship. You are going to need a mix of all three ship types in order to win, as each ship will have at least one ability. Also battles will last a little longer so it gives you time to make better informed tactical decisions.
