While i am literally giggling right now at the thought of hundreds of highsec tengus becoming useless, it's the wrong way to address whats going on in highsec exploration - because those pilots will soon discover the Cerberus, or similar boats.

Randomizing of signature strengths and/or looking at loot tables (why are the invulnerability fields, as active hardeners, dropping from 4-6/10 sites - it would have maybe been better to put them in 7-10/10 sites - but then again eanms are sort of their counterpart, so i dunno) would have been much better.

Removing 4/10 from highsec would also be an option.

If you restrict access to those sites, be even more strict and disallow also t2 ships and pirate/navy variants.

T2 cruisers don't have scan bonus, they have lesser tank and dps than T3. Also some of them have problems with exploration fittings (Zealot with 6 High\turret slots as example).
T2 allowed in exploration sites? It's ok, players now have the good reason to train for Heavy assault cruisers while waiting for proper rebalance.
It's not just current dumb "Train Tengu - the only ship you need in your lifetime to do everything better than anyone else". Let's see how painlessly current Tengu addicts will switch to Cerberus if ships are "just same" and "this will change nothing".

If you can fly a Tengu you can fly a Gila, which is more than capable of doing 4/10s. Stop acting like the world is ending.

Every once in a while I find myself doing a period of hisec exploration. Just resubbed so I'm bulking up the wallet a bit before heading back to null.

And I've done my fair share of low and null explo as well.

Some of the most adrenaline-filled fun I've had is getting into a GSO only to find another t3 there, and then competing with them for the bacon at the end. The risk of some good pvp here is a lot higher than some might expect, especially if I or the other guy decide to steal from the can at the end.

Well I suppose now that t3's won't be allowed it'll be a lot quicker to kill whoever tries stealing those cans. Doubtul this nerf would stop any of this farming behaviour though. There will be a very SHORT period of adaptation and things will be the same again. Maybe even worse!

All those whiners wanting to pull more targets into lowsec....you know, it's usually not worth the time it takes to complete any Watch or (especially) Vigil escalations. More times than not, no loot drops. So all the arguments about the payout for risk are...invalid.

Realistically, i-¦ve never used so many probes to get a target, 7 or 8 is overkill and just shows lack of dimensional awareness and basic geometry.
Pre-set patterns are cookie cutter and do not really have a place in a sandbox, it screams hand holding and guidance (which should be confined to the rookie tutorials),. i know CCP will not listen to players as they have committed them selves to this shiny, shiny broken poorly developed new way (two teams not talking and working together on a basic common linked interface at the coding level screams trouble), but they can get it right in the next two weeks even if they have to recode some basics from scratch.

Single probe launch is a fundamental requirement in exploration, as i have said before, make Extended Launchers firing base be 1 combat Probe or a set of 8 Core Probes,a.k.a the Super Probe and up the Core Probes mass to 1.25 to bring consistency, its logical, PvP probing requires far more flexible approaches than find a PvE site.
