Tarvis: Just one thing to note, the time it takes for your lasers to charge back after transferring them to Shields is the same amount of time it would have taken the Shield Recharge to charge that amount of shields. It's all equivalent. Getting shields from lasers just SEEMS better because it's instant gratification. If your lasers are totally drained but on max recharge rate, and your shields at maintenance level, and you direct lasers into shields as it charges, it will charge at the same rate as maximum shield transfer is.
Also, if you have both lasers and shield recharges on max, it makes your shields charge twice as fast if you sink your lasers into shields as well.
The whole point of having all the options is to allow you to prioritize survival and evasion VS attacking depending on your current needs. When you shunt lasers into shields, you are losing your attack capability for some time, whereas if you charged that amount with the Shield recharge instead, you would not lose it.
