Is this advisable for leveling? (I am talking about the skills like escort captain, cruiser captain, etc....).
I have heard some debate as to whether or not these skills are worth taking since they are only good for one tier of play.
I think those are points well spent, as they give you certain advantages over the appropriate ship-type., and that might tip the balance in a space-battle.
Granted, you should only specialize for one ship-type per tier or you would really waste points, but that's the nature of a specialization: for being exceptionally good with one thing, you are less qualified with others.
For the tacticals who go for escorts (like me), spending points here does help enormously to turn the ship the way I need it to a) maximize the damage on the target and b) minimize the damage taken myself by offering the enemies always those sides where the shields are fully up.
It's a little dancing, and for that I need any turning-speed I can gain, so those ship-captaining-skills are the first to be filled up completely followed by the ship-weapons I prefer, together with the ground-skills.
Well My thoughts are on the issue is that it's good to put them in starship command and then what ever type ship of the LT cmdr tree you are going. Reason being, the others are more specialized and help only that type of ship where the first two tiers apply to all down the rest of that tree. More reason to this is since we only get 8000 point for our admiral tree, I'd like to use my points in other areas of the tree than having 9 points go to waste (if maxed) in something that becomes obsolete once you get to next tier.
This is also coming from some one who puts all points in space and none in ground if it can be helped. Honestly I hate ground combat, it's less common and even with no points in it and being a commander i have no difficulty doing missions at all. As long as I keep my BOffs skilled up i've been fine. That's just my 2 cents, putting the 9 points in each tier does help for those 10 levels, but in the long run i feel they may help in one of your subsystem boxes or even just to give you more diversity in the end of what you can do.
