I've noticed that for everyone of my 4 officers, if i point 1 point into any of their skills it makes the skill WORSE, and if i put in points, it leaves it the same as it currently is. Anything over 2 points and it actually starts to improve.
If i have high yield torpedo and its at lvl 2 and i try to put 1 more point into it, the Recharge time goes UP 5 seconds, instead of down. If i were to put 2 points in and then assign them, then the first point raises the recharge 5 seconds and the second point lowers it 5 seconds, so there is no improvement. If i were to assign 3 points, then the first raises it, and the next two drop it for a net yield of -5 seconds for 3 skill points.
If i always only assign 1 skill point, it appears that i'm only making my skills worse and worse.
I've bugged it. Be aware though, even though it says the cooldown goes up, the cooldown does indeed go down. Level 9 skills supposedly have 35 second cooldowns according to my skills page, but they are at 30 seconds when i use them.
