Arrowing teammates is to not let the pker get the kill, while also getting a kill yourself. It was made with that in mind, instead of dying by spikes. Same goes with bombs.

Why is MoD so popular? Because it's harder to suicide. You go to the flag, and no one really tries to escape to go to some spike. If anyone is that obsessed with not letting you get a kill, then they run away for someone else to get them, but that isn't really always the case in MoD compared to Sards.

Deadwood, MoD, Swamp, what used to be Snow: At flag = no suicides.

Castle, people will run out of flag room at 0.5-1 hp, go into house, kill with bomb.
Now they have full hp, and can continue to pk, without dying.

Sards, spikes.

York was the barrels.

None of these are good, even the pker can do it. Doesn't help anyone enjoy the game. "They do it, so I'll do it too." or "I don't want them to have fun, so I can afk and get my hat."
