I don't think any of these ideas "break" the system..... some allow more options than others..... but as far as games I have been in go, the CR still manages to balance things out.......
I posted this on another Forum (Starship Combat News) but I think it will also fit here..... Remember, you can build the most awesome 20 hull level 8 technology monster out there, and still not win...... There is a final variable that most people don't consider..... the "to-hit" roll.
The weapon may be 3/3/3... but if you had to choose a 5+ targeting, in order to fit it, don't expect to count on it killing someone every turn.
Here's the story.......
Ok, recent game of Starmada. My fiance and I were fightning and decided to use the same forces on each side. Basically 1 heavy cruiser, and 2 lighter ones. We ended up pretty much closing on each other through an asteroid belt, and it became a classic line battle. On my left one of my light cruisers engaged hers, and they both vaped each other in the first turn....... total destruction. On my right, the two cruisers proceeded to damage each other, but could continue to the next turn. However in the Middle, where the two heavies were setting up, we had the most impressive display of weapons that anyone could ever want to see (we decided to run this battle without fighters). Unfortunately, neither ship could seem to hit the other.
Round two, the two light cruisers continue to pound on each other, and due to some impressive luck, hers loses all of it's engines, while mine still has one left. Meanwhile the two heavy cruisers pass by each other at one inch apart, blazing away with everything, and nothing hits....not weapons being stopped by shields, but specifically, that every weapon fired misses. By this time, I am a little frustrated, so as part of my orders for next turn, I intentially give myself a crew hit, and eject my gunnery crew. At the same time, my new bridge crew notes that there are little objects being ejected from our opponent cruiser..... her gunnery crew (we had a ref, and our orders were secret from each other) The light cruisers finally finish their fight by destroying each other's weapons and engines, so they are now sitting 2 inches apart, can't move, and have nothing to fire.
Finally, after 3 more turns, our two heavy cruisers managed to work around the asteroids and go at each other again, and we both open up. This time, only one weapon from each ship hits the other, and both roll 1's for the shield penetration roll......... At this point, my captain offers hers a deal, she can tow away her remaining light cruiser, I'll tow mine, and we'll call it a day......
