Title says it all.

actually it doesnt.

im going to assume you meant ANY good

and then it all depends on alot of things such as your attack and how many other sabs in your legion

Sorry about that. Yes the title is meant to be 'Is Zolazin Sab any good?'
Well if I changed I will lose a lot of my PvP advantages (attack and hull) and I want the ship design 'Incubus'.
We have no other Sabs in our legion...

probably just about worthless then

Only one sab is kinda useless, you need at least 4 people for this to be effective. However once you can get a group going, it becomes very useful.

yep unless your attack is really good a solo sab is rather worthless, though there are plent of high ranking legions that are always on the look out for another sab at arms.

Im a rank 680 sab, i find it gives that little extra edge for plant thefts, and of course its great to help out the others in the legion.
While 4 or more sabs is ideal, even 2 can make those invasion chances much higher on most planets.

Note-i am only a sab at this rank to help out the team

I'd try and raise some interest for more people to come together and become saboteurs than to just dive in alone. Alternatively, join Galaxy Wombats. We have a strong saboteur team (Of which I am the co-ordinator) and could always use another sab. :3

after i reset i will be a sab for a bit, mostly for the medal and that ship look. but alos to help the legion a bit. It's a ream player job.

yeah like others have said its mostly a team player option.

only personal benefits that i see are:

can sab one time on planets you are invading(of small use)
getting into bigger legions that lower their requirements for sabs
and sabs often are the next in line to try a planet if the first person fails and before it goes ffa

Your resetting? O_O Good luck.

Ok anyway thanks for your advice. I decided I will become a Zolazin Sab and try and help my legion with its ability even though I may not do much, but 1 little help can make a difference. But before I become Zolazin Sab I must do the mission chain and get a good unbuffed ship. After I get the ship design Incubus I might change back to Konqul Fixer or Excavator, depending on how good Zolazin is. That leaves me with 1-2 glaive devices so then I'm thinking to change to either Drannik or Taltherian.

Thanks for your advice.
