Ehhhh I find the combat tree to be more potent than that, if you really want an indication then battling a ship with an officer vs one without is very noticeable, also try running a simulation on a ship with and without a high ranked pilot, it makes soloing with a decent ship a lot easier if done right and the benefits compound.
I tried; not impressed with the results. Ships still run away from you. Multiple capitals will still wreck you (except maybe for Paragon flagship). If I take Paragon to kill capitals, the other ships will kite and run down my CR (because there are many), and there is little I can do about that. If I take a faster ship, it is not powerful enough to kill everything, if it can survive getting hammered by capital-grade firepower.
With Unstable Injector as it is, combined with smarter AI, player cannot kite-and-snipe to the extent he used to.
The biggest problem with soloing in the past was time taken to finish fights. But soloing fleets was extremely efficient in supplies consumed, and until 0.72, AI did not kite much. In 0.65, I used frigate hordes of about 40 ships at endgame because while they are a bit less efficient than soloing, they finished fights much faster. In 0.7x, officers made ships without them useless, and the enemy had many more ships than you. Soloing or chain-flagships was the only way to win without losing too many ships.
As for officers, better to get Leadership and then get ten officers and deploy all, at least with max battle map size. With few skill points, it is more efficient for me to get fleet and campaign skills and delegate combat stuff to officers. I want to hot rod in a big ship with combat skills, but I cannot afford that (more than Gunnery Implants and Helmsmanship).
I guess if I used normal battle map size, I cannot deploy more than a few ships. Paragon, then 30 more DP left? Forget that, crank battle map size to the max for 200 to 300 DP limit. Even that is only enough to deploy about half of my clunker fleet (of capitals, cruisers, and carriers).
If soloing or chain-flagships will be barely more efficient overall than fleets, then just deploy fleets and get combat over with quickly.
@ FooF: I am still steamrolling bounty fleets with few causalities with my completely unskilled character. My clunkers tend to have three or four damage mods and are outfitted with stuff mostly from Open Market.
I am beginning to miss using pristine ships with elite weapons. They are too rare to use without easy access to more military markets with a commission. I use mostly clunkers out of necessity.
