It depends on the stalker, some stalker powersets have perception powers, SR and Ninjitsu if i remember correctly. You could have a lot of fun spooking the other sets though

thing is though, people expect Stalkers to go invis, not other AT's. Well, actually I expect Villains to go invis, a lot of villains seem to use it. Would be interesting if some heroes used it though, as many villains are not prepared for it. One +perception power on Stalker secondaries is not enough to see through invis as far as I know.
I used to have invis on my Ice/Ice blaster and used it to great succes in big arena free for alls. Kinda like an early version of the Stalker I guess. Dropped it after ED though, there are just so much more powers that are critical to have now. No more room for "fun" stuff. Thanks Cryptic.

Is Illusion controllers Superior invisibility any good these days? I thought it used to be.. But that was before +percep...
Superior invis is still good, i'm rarely spotted until i attack.....that or they just ignore me coz i'm useless
I miss him in the weeping of the rain;
I want him at the shrinking of the tide;
The old snows melt from every mountain-side,
And last year's leaves are smoke in every lane;
But last year's bitter loving must remain

the numbers of the powers are discussed here
the upshot is, even someone with the lowest +perception they can get (one small yellow insp) can see a non stalker from about 50ft. Someone with a +perception power will see you from something like 250ft. (its a pretty similar story for stalkers who just run hide, but they can stack powers and have a much higher stealth cap which is where their advantage comes from)
I usually run group-invis, which is the same invis number as superior invis (but when it supresses it stays supressed till its reapplied).
I work on the assumption that everyone can see me unless I keep my distance since most have some form of +perception in the PvP zones.
Most serious PVPers will most likely have Tactics, +perception in auras/powers or in the case of scrappers Focussed Accuracy.
If you don't want to be seen with invis try Bloody Bay as you may stand more of a chance in there but the higher you go in PvP zones the less effective it will be but not totally useless.
If you want to go for invis then get stealth also so you can just drop to that when you are ready to attack.
My scrapper has Tactics and Focussed Accuracy ready for Recluses Victory and from test I can say it's very effective (unless stalkers go for hide/stealth/invis combo). A normal stalker with hide and stealth that cannot be seen very easily even in Warburg stands out like everyone else in Recluses Victory
Also I spent many an hour with my ss/inv Brute in Sirens Call/Warburg and could see normal stalkers (ones that just use hide) and trollers with Superior Invis quite easily with tactics and the + perception in one of his auras

bloody /nin stalkers seeing right through my sup invis without them having tactics. Can't believe they just stock up on yellows to hunt me...
afaik, stalkers dont need yellows to see thru invis or superior invis when they are SR, wouldnt know about the rest tho. Any player with tactics can see thru, and so does any scrapper/tanker with focused accuracy 
Well i use invis on my blaster but its seems to be abit on the rubbish side in the pvp zones we have.
Saying that in RV on the test its very nice i can get right behind a villian drop aim and build up then fire of a nice zapp taking most of there health away before they can do anything, follow that up with a thunder strike and i have one dead villian.
Kind of makes me feel abit like a stalker doing it
A quick question as a blaster I would like to know whether invis in pvp is any use in avoiding stalkers.
It would be good to get the jump on them once and awhile.
