But mainly the raiders get angry when people do not know tacs and when told what to do cant even follow instructions. Tank pulling elegons protector outside pre 25% like at 90% instead and not pulling it in, making it blow up inside. spirit kings where tank rushes off alone with no strong cd up so he can actually survive that shit, better even he should just chill and run with the group.
That list could go on and on but you can see why raiders get mad sometimes, lot of crap happens in lfr. Thus raiders get angry at the casuals that go in clueless on a fight bathing in fire and so on.
