If you can’t, then play BF, Post scriptum, or HLL and call it a day. If not then cope, seethe, mald 
Well greyzone is out of bounds for certain teams, simple lol.
Did you play Gaijin’s inferior game called war thunder? They have no greyzone and what happened? over 5 tanks spawncamp on your ass waiting to kill you 1 second after spawning… Tank’s greyzone and hiding in buildings is their only strength since they suck by a ton when they are shoved in playing field. If they are forced to despite being weak, then the playerbase will shift to planes.
Trust me, Planes are more terrifying and op with constant bombings and shit than a mere 2 tanks HE spamming. If people complain and force DF to increase it, then its gonna be worse…
Well that is up to you to figure out good locations, normally in city ruin maps there is no greyzone camping since most of the time their view is blocked by buildings.
What? Are you BR 1 guy? In BR 2 or 3+, you will always find enemy and allies aircraft since they get good planes there with good loadout. Aircraft are a bit better than Tanks since you don’t get yeeted by Tnts, and their AA gun with less skills sucks. Only way to beat it is to be aircraft yourself.
What? They last more than 5 seconds and thanks to good teammate, can last forever. You just need good memory skills. Marking it by spamming v is easy if you slow down, get to 1k or 800ft in altitude and do a 45 degree or flat dive.
Sounds like a lazy guy or a skill issue guy. They ain’t worse than tanks one:
“Sorry, but I can’t sit there for whole game zooming, looking for enemies, yeeting out of my commander hatch, repair my broken tank, spamming v on suspicious zone to get clear picture, and praying that I don’t get shot nor getting blown up by random tnt charge and tnt packs.”
SUPER EASY SOLUTION:
- Wait for high BR AT guns, Use AT guns in low br
- Use AT rifles or rocket
- Planes
- Go to greyzone if near as sacrifice
- Mark it for others to do the job for you
- Be a tank yourself
And yeah, keep Greyzone as it is as it makes the game fair and good since you can counter it too.
