As a Tactical Captain myself, I have noticed the enormous power I have over other Captain's of different classes. Coupled with obviously over-powered vessels such as the JHAS or Fleet Defiant and it becomes a deadly "synergy" of its own.
So lets stop this talk about "re-balancing Engineering and Science" which quite frankly, we all know that Cryptic are just not able to do. They've had 3 years to balance the classes and have failed and proved they are not interested in that.
The most simple solution is to nerf the damage that Tactical Captain's are capable of. Stop Attack Pattern Alpha from interacting with Science Abilities by locking it to "WEAPON DAMAGE ONLY" and nerfing it to 25%. Also Go Down Fighting should also be "WEAPON DAMAGE ONLY" and nerf the durability of Escorts by 15% across to board to become the Glass Cannons that we all know that they should be.
These topics about changing skills etc are really not needed because it just brings us away from the main issues. Tactical has been too powerful for too long and are Cryptic's favorites because they do not know how to do other abilities without making damage ridiculous.
