Being constantly tracked is effing ridiculous. Every other game that has a form of CC has immunity timers. Being tracked nearly every shot is a joke and a poor game mechanic.
This is not a CC. CC implies you can't do anything to hit back... and this is not a MMORPG so even using that term makes me feel silly. Not to mention there's not a whole lot small tanks can do to a big one other than keeping them tracked, and even then it's difficult at times because you can't damage the tracks enough.
There's only 2 situations where you get perma-tracked.
1) someone's actively hitting you constantly in the tracks, which means you have a clear line of sight to shoot them back. Every time they shoot you to track you, that's one shot that's not doing any damage to you. You can shoot back and kill the annoying fly and move on.
2) there's 2-3 guys shooting you. In this case you're fucked anyways because you managed to separate yourself from support or are the last man standing. (multiple arties hammering you applies to this situation)
In both cases you can fight back. If there's a small tank circling you, clap for him because he's a good driver applying good tactics. Honestly they've fixed tracking so much, it used to be way worse.
edit:
Have a D1. It sucks horribly. If I wasn't saving free exp for e-75 modules I'd spend it on the frenchies to get past this sick joke. After playing the french low tiers I found myself enjoying my Lee immensely.
