Can we get rid of the lone ranger type attacks that kills a spawn vehicle in 3-5 seconds, please?

Not FUN feature of the game.

More fun than using a Lascannon.

Can you stop leaving your spawn vehicle not defended?

That a Featured Feature of the game.

The meltagun is way too strong, a single person can destroy 2 or 3 transports before anyone has time to notice.

Yeah...cause you've never seen a FD or Slaanesh Marine make a beeline right at your transport, dropping an uncounterable meltabomb and hitting LMB while circle strafing around the vehicle using it as a shield, taking out the transport even if they die.

Added Bonus: Melta users are using those pesky tanks that no one likes to fill up and use them as personal transports to drive up safely to a protected vehicle, pop out and proceed to meltabomb/melta it.

They don't care, 15 second respawn<destroying a 3-4 minute respawn vehicle crucial to attacking a point.

The only "real counter" to this is to constantly drive your vehicles which is only fun to a small faction of people and definitely not rewarding at all. Even then you can still get melta'd enough on drive bys to eventually die. Eldar vehicles are probably the best at doing this though(fucking road kills...)

Who cares about the defense, the spawn vehicle is destroyed before they can kill you

You want to make "defending" your transports a real thing? Make meltabombs able to be disarmed if you get it to in time.

Either disarm them, with an XP reward, or pull it off and throw it clear of the tank.

lol and who is gonna be alive long enough to disarm it .... plus that would make the bomb almost useless for vehicles
