Find guild, do raids, item will drop eventually, if you loose it to your guild mate, you will get it next time.. profit.
It always been like that.
If your guildie is lucky with insane rng loot, good, he will boost your raid.
Now you also have options or possibilities to get raid quality loot outside of raid and its bad cause it is RNG?
You dont have to do it at all.
God, you can ding today, get crafted gear, instant 850 gear, with best stats (which is huge thing), only have to work on artifact knowledge and farm AP, and there is almost no RNG. DO class hall to unlock 3rd trait, meanwhile get every relic you cen get, and there are plenty 830-840 (WQ,hc,myth..) ones, while you are waiting for class hall missions.
CG you are now ready for HC raiding, in like 2 weeks, yet these QQ threads about rng..
