Atleast now when you're out and about with an infantry squad and a tank shows up, you're in real trouble. No longer "let's all respawn as L-AT and someone get H-AT from the RP". Now, I actually sometimes find myself giving the order to take cover, and pray that the tank will pass or that a team-mate with something capable of taking it out shows up.
If it's a solo-tank, it's sometimes possible to smoke and rush with an engineer, but a couple of supporting infantry or a 2-man tank ruins that plan, leaving no option but to keep your head down and prays that the big bad beast goes away, as it should be.
