Something warranting seven and more wipes look quite a Normal-kind of difficulty. I mean, let's not forget Normal itself ain't anything crazy right now. But auto-queueing brings a number of issues. There's a reason if Mythic dungeons aren't auto-queueing based. And while even Heroics can occasionally be tedious at the beginning, the limited number of people involved diminishes the issue.
That's not going to punish afkers, it's going to punish everyone by increasing the weight these idiots bear for the ultimate success of the encounter. I have no intention to rely on "well, they'll eventually learn the lesson" by wiping on loop for who knows how much time. Because, honestly, I don't give a flying shit about them. If "punish them" most likely mean undermine my own experience then I couldn't give a crap if their laziness gets rewarded.Even lfr players say it's too easy though. Some also want sth remotely challenging in lfr, even if the only challenge would be to not afk for 30 min and expect rewards afterwards.
And I don't think people saying "LFR is too easy" understand the issues behind an auto-queueing system applied to raids. It's the typical proposal that sounds cool on paper but could turn into a literal disaster on live. On the end of the day, LFR is there just to see the content, not to offer challenges, let alone it can be a decent entry point in terms of gear for anyone planning to do serious raiding but is not carried by X guild. I'm not in favor or against the removal of the feature, I'm fine either way. But considered the way the feature is intended to be, adding "challenges" and "learning curves" could pretty much become only worthy to be removed.
Mind you, I'm not entirely against the idea to make LFR a bit more challenging, but I can assure you I have no intention to wipe 7+ times in a row playing something I don't find madly entertaining to begin with. In that case I wouldn't waste a second of my time on LFR, either doing Normal, Heroic ecc. or not doing anything raid-related at all (depending from my situation).
