If you take out rush, then the game will just be long range spam.
MWM Spams, Plasma Spams, every fleet under 0.1 speed, armor tanks, lures… Wait it was already like that in the now dead competitive play. Fleet with 6 MWM per ship could already crush CL rush like nothing.
I went with QB/RFL because they’re relatively cheap. Not so much in terms of module cost, but in support cost. The much-maligned Quantum Blaster and the Rapid Fire Laser require such tiny investments in power and crew that I find they are often very useful in filling small gaps (“Well, I have one hardpoint, 3.2 power and 6 crew left.”) I’m not saying they’re the most effective things in the game, but they’re far from useless.
