Just to chime in on this. I noticed that the higher quality BOs I've gotten often have rank 3 skills so I decided to look on the exchange and see if I could find one pre-trained with HYT3. Long story short, it looks like the higher quality BOs have a very limited skill set (it looks like there are only 3 or 4 variations ofr tac officer skills) and none of these include HYT3.
I am on the slightly opposite side of the HY III part. I am a tactical officer in a cruiser. I did train up the skill to get HY III (being aware that I would only be able to use it in an escort ship though) mainly because I wanted the higher torpedo damage bonus, plus for when I buy an escort class as secondary ship some day.
The problem is for my cruiser-career I wanted to unlock Emergency Power to Shields III as well as Emergency Power to Weapons III. the former I already spent my skillpoints on and have since been wondering why it didn't unlock the ability for me (not that I could use it on my main engineering BO as he is gimped due to having aceton field I as his rank 3 space ability which cannot used or even removed, which cryptic claiming it is working as intended).
On the good side, I am at least benefiting from the additional shield system power setting granted by the player skill that was supposed to unlock that emergency power to shields III ability.
I guess it is save to assume that I as a tactical officer won't be able to unlock any of the other level III abilities that I had planned to use either (those being emergency power to weapons III and directed energy modulation III)?
Ok thanks guys, it kinda sucks really considering the skill says reaching all 9 ranks gives you the ability to train officers in HY3 when it should say it gives Tactical Players the ability to train.
Well, looks like my escort is gonna be slightly gimped from what I like.
