I am thinking about using my heghta bop as a tractor beam bop aka grappling hook to assist my fellow comrades in cruisers or carriers in Kerat zone
The idea is something like:
bridge powers for tractor beam, mines/torpedos that can slow down the target, gravity well and eject warp plasma.
Would it be practical?
The problem with BoPs, though, is the lower shields and hull. Chances are, you're going to be targeted as soon as you tractor someone, so they can get away. If they have Subspace Jumper, and an Escort, you'll be in their forward firing arc immediately.
Regarding TBs TB3 is 17 sec duration. TB cooldown starts after TB initiated. Meaning 3 seconds before you can apply a 2nd TB. So, yes you can be effective w/TBs. I'd throw a PSW in there to serve as an interrupt.
Also, I had a torp/tbr build awhile back for the B'rel which I made an effort to never decloak. I was exposed when tbr was active or a fire a torp, but still had cloak defense and movement and damage bonuses. You could try something similar since now you can stack PH and HE etc. You wouldn't need shield buffs either freeing up some Boff slots.
Various hull resists buff you could try and incorporate:
7.2 part borg
8. Aegis engines for more defense while cloaked/2part aegis 10% boost
In the end going all CC w/o some damage will likely not be as effective as mixing in cannons, but that kind of stuff is fun for me to try every now and than for a week or so.
I am also putting together a tractor BOP. In PVE it works wonders, my team loves me every time. I have not been able to try it in PVP yet though, still a level or two to go. Anyways, it will probably be great against cruisers and sci ships, but escorts will just omega pattern out of your firing arc. So what I do is try to make it that much better against cruisers.
If your toon is a sci, max out sensors too, put a bunch of consoles into sensors so that you can put a huge dent in their damage resistance. Use disrupters to attack that goal as well, since the goal is to do a bunch of damage in a small space of time, disrupters are great anyways because you should be attempting to not let tac team or emergency power to shields/reverse shield polarity stop you from putting them into hull healing emergency mode.
The Somraw, K'tinga, D'Kyr, D7, Kumari, Xindi carrier, Xindi escort, and the T'Varo are all older than the Constitution Refit and yet they are tier 5. The rule needs to change.
