I have not played STO for probably about a year or more, and was wondering if anything major has changed in that time, i noticed that its F2P witch is nice, but anything game mechanic wise that is different? I am currently playing my tactical / escort character. Any advice or heads up would be appreciated.
As far as updates are concerned, here is a list of the most important sto updates.
For a tactical / escort build, you're main focus is to deal as much damage as possible but also survive as long as possible. Honestly, if you are only going to do PvE (not including STFs) then you don't need to worry too much about your build.
