Prevent graveyard farm on AV / WSG?

problem1: When opponent teams in WSG are little unbalanced, graveyard camping begins, and usually lasts for the whole BG.
After graveyard camping begins, for the losing side its hard to recover as some players leave bg, some players just go afk.
Its not even fun for the winning side. Yes they get honor but ruins the fun

problem 2: I tried AV as horde like 10 times, it was 10/10 a chaos, i could not go beyond the first graveyard.
After that 25 ally players just graveyard farm until killcount goes off and they win. Losing team also cant recover from this.
Also on AV mostly ranged chars dominate, so graveyard camp is even worse.

I do believe this could be made a little better with some adjustments.
Exactly what adjustments? Well that's what i'm afraid to suggest as ppl will come and say why its bad.
So please if you got any good suggestion post that.

I thought of things like :
-buff after resurrection : -50% dmg taken, immune to stun and movement imp. effects for 10-15 sec.
-buff after resurrection : invisibility and invulnerability for 10-15 sec. (so u can move away from campers)
-increase the area that you can resurrect from your corpse location
