My guess is that they designed that to push non raider to try to raid : if this was the planned difficulty (extreme), it might have worked. People were asking for BA DRS lvl and content, and the rewards fits that. But they went overboard and went to savage lvl, and didn't change anything. Thus
- The rewards and restriction are misleading. It seem anyone can try it, but the reality is that it's not : it's a content aimed at raiders. They tried to uphold the confusion to some degree, which lead to many being disappointed when it released.
- The whole bonus thing has become useless : in a fight with body-check that can make the alliance wipe if one is dead, which raider in his right mind would let people that never raided join (I don't blame them). You don't want your farming parties to last as long as your first one. The bonus is low, so it's probably better and faster to do 2 runs with people that know the fight that risking to have players that make you wipe. They totally ignored how people play once again.
This whole raiders helping the casuals cannot work in a fight that's so punishing. Could have worked in BA, could have worked in DRS, but doesn't here. The idea was great, the implementation is awful.
It's a shame because in the end, very few of the complaints I see are about the fight itself (except the body check one : it's already a pain in a 8 men, so with 3 times that...), but rather about how it's unclear who they wanted aim that for, about the fact it's onother high end raid, after already getting Extreme, Savage and Ultimate in this patch while non raiders can go to hell, and how long the content is gonna last because of those problems. There is also the "don't put haircuts behind savage, especially not the contest ones : if you send the message that the haircuts/weapon might be locked behind high lvl, people might stop to engage with those".
Once again SE achieve to do all the right (wrong) choice to get backlash from a content that is, overall, pretty good for what it is (it seems raiders love it).
