- Newbies don't pick up on it very fast. I think this is partly because of the psychological anchoring of the default settings. Shields start at 400, 1000 is over twice that, 1000 must be ridiculously high shields. Ah, newbies.
- Overclocking is lacking. There is no weapon overclocking at all. Shield and engine overclocking are broadly moving targets. Is 400 GW into shields a lot? No powerdock, 400 GW is desperation. With powerdock, 400 GW is "our capacitor is full". It's hard to balance this.
- Core stability requires very little decision making. There are tricks to squeeze power from core stability, but they're very robotic to do so. Raise core, wait 30 seconds, lower core, an AI could do it.
- Managing core stability is rarely an issue. The only reason it would ever become an issue is if you intentionally make it one. The benefits are relatively small compared to the problems in doing this.
All consoles manage their own power now. Engines consume less power if the throttle is lower. Weapons doesn't consume power unless they're firing. The engineering console is now responsible for how effective these things are. Instead of setting how much power they receive, you set how 'effective' you want something to be. Effectiveness is measured in %, starting at 100% and ranging from 0 to whatever by increments of 25%. Set shields to 200%, get more shields. Set weapons to 200%, weapons shoot faster. Increasing a component's effectiveness doesn't directly affect power drain anymore (but it does indirectly raise it through heat).
In addition, there's two new mechanics to replace core stability: heat and coolant. Unlike core stability, every component has a heat level associated with it. As you use a component, it generates heat, and if you overclock something, it will get used more often, resulting in more heat. Overclocking also passively increases heat generation.
What does heat do? Aside from side effects (which can be good or bad), it increases the amount of power that the component needs to work. It can also eventually shut down that component entirely if it gets too out of control. Overclocking your engines lets you get away from danger fast, but it will kill your capacitor in the process and leave your engines glowing hot for a while.
But fear not! The BC now has a supply of coolant it can use to fight overheating in a pinch. Coolant refreshes itself slowly, like one charge every 90 seconds. Once it's used up in a fight it's probably time to start worrying. Coolant is powerful enough to keep your shields frosty while they repel broadsides, or give you every ounce of firepower you need to obliterate your opponent.
So, the engineer would ultimately have more responsibilities, now that they have to manage coolant on top of giving components more oomph when it's needed. Teams would now need to communicate more to handle power issues. The BC can be more easily balanced against everything else, averting the current 'faster than a miner, tougher than a destroyer, more guns than a corvette' BC incarnation. Basically, it would pave the way for more teamwork-focused gameplay.
