Fire on my mark and Tactical initiative really aren't so good by comparison, still useful but not so gamechanging. Damage resistance debuffing doesn't do any good if the target isn't stacked on resists to begin with, and reduced tac officer cooldowns isn't so useful when so few of the tact abilities are truly useful compared to the number of officers you have available to cast them.
Fire on my mark makes them take increased damage resistances or not, I should point out. Also, Tactical Initiative seems to be broken in space. It doesn't change the CD's at all. If I used it prior to activating the skills, no difference. If I use it after activating the skills, no difference.
