Tag up with one of your alts before grinding at a spot. The alt you tag up with must not care about losing experience on death. Now go with your main and check if your grind spot is available. If it is, go ahead and claim the spot. Activate experience boosters, and have a blast! When a red player decides to steal your grind spot by killing you, and you know you are not strong enough to send him to jail, swap to your alt and keep killing mobs there and let him kill you whenever he tries, until he eventually gives up. The benefits of this approach: The buffs on your main are paused, so you can continue your grind after the red player is dealt with. You have nothing to lose on your alt. If he attempts to let you suffer a PvE death, you couldn't care less. You cannot lose experience or crystals on your main if you play on your alt. The red player keeps losing karma and goes deeper and deeper into the red. Afterwards, you can just swap back to your main and grind like nothing has happened. This approach is especially beneficial if you run 530% boosters and other important stuff you don't wanna waste time on. Happy grinding!
