Not really worth it, almost everyone has enough perception from tactics+perc IO, or someone buffing them.
There really is no good stealth moves worth getting for their actual stealth capabilities unless you are a stalker because of all the +perception found on a pvp field. I believe superior invisibility gives the stealth cap as well on a controller but I have never tested how well it works. I personally only stealth moves for the defense stats typically associated with them.
During the downtimes, I've been trying to read up on Smoke Grenade. Once again, there's a lot of old information.
I know Smoke Grenade has more success in PVE than PVP, but I was wondering if anyone currently has tried using it Pro-i13. I did a search on it, but didn't see anything related.
Just some questions:
1. The Smoke Grenade attack won't help you if you use it after another attack. i.e., you can't go invisible until the forced timer expires and allows your stealth effects to reactivate, right?
2. If the smoke grenade actually works on the target, does it seem to be useful in PVP?
Overall, if you have any experiences, good or bad, would you share them for insight?
