So basically normal modes?
It's something I've been thinking about for the past few weeks, but, the intent of LFR is to be for people who want to see the raids but can't commit to raid times due to real life. The only reason the difficulty is so low is because it is, well, nearly impossible for a group of 25 complete strangers in a game as big as WoW to be placed in a group together and actually deal with mechanics. It's the reasons 5 man heroics went back to being a cake-walk this expansion, or have we already forgotten what LFD was like at the very start of Cataclsym?
So, my question is, what happened to wotlk style normal mode raids? Naxx was easily* puggable at the start of wrath and while Ulduar didn't really see that same treatment, both ToC and ICC became something you could just gather up fairly random people in trade chat to go and do. That went completely away in Cata for the most part. At launch BWD and BoT normal modes were pretty rough for the average player, who, were having a hard enough time finishing 5 mans anyway. MSV/Terrace is a bit closer to that wotlk style (HoF had some crazy enrage timers for normal modes), but, I feel like the addition of LFR probably made a lot of the playerbase not even want to try the real deal, but, I dunno.
Anyway, if I was working at Blizz I think I would try to tone down normal modes into something that is very pug friendly from the launch of said raid (and make normal mode versions of raid Cross-realm group-able from launch) and smooth out heroics to be something a higher percentage of guilds actually worked for since the amount of people actually doing heroics is pretty tiny anyway. I feel like Wrath had a good working model and people seemed to be really happy with it. LFR can still exist for people that don't have the time to even look for a PUG but, I think the purpose of normal modes has been swept up by LFR and transformed into something else.
*not lfr easy, but the average competent player could do it.
