Simple, once you go out of grace you get flagged for PVP for 10 min. No 45 second disgrace period where you are immune to roots and special attacks because you are standing in 75% under 25% rules. You crossed the line, you made your move you are now flagged for 10 min or untill you die, and vunerable to every type of attack/nano/special, regardless of what gas you are in.
PT2
When more than 10 people assemble within a 40m grid and within 1000m of a tower, all get flagged for PVP for 30 min or untill they die.
Death to llama tactics. Bring the fight with some Huevos de Oro.
