Guild Wars 2

I’ve seen people mention rally botting. What is it? Is it using a cheat or what?

tl;dr answer, rally botting = feeding.

Comes from WvW, zerg busters (organised WvW guild focused on killing trains/zergs) would target rally bots so they can get downed guildies up. Rally bot in pvp is a player who goes into fights, doesn’t do anything (useful), getting downed and stomped so enemy team can ress off of them
