I'm a semi-hardcore/semi-casual (dunno which to call it :P). Raid Lead of a 6/7hc guild that is working on Rag-hc that raids 9hrs/week (3hrs/day for 3days). I min/max as much as possible to obtain the most out of my character in raids.
Just to be clear, I have no problem with the incoming nerfs or with the LFR easy-mode addition, as long as they are both handled properly*.
* A Caveat to allowing both of these is that:
a) Blizzard really should've announce the nerfs at least 4 weeks/resets in advance. Whilst it does not affect me or my raid group as we killed the heroic bosses pre-nerf (bar Raggy), I still feel for those that are working on those encounters atm. With enough of an announcement it would allow guilds to push/plan better and hopefully reduce the resentment fostered by this change by at least 50% (can't really hope for much more ).
b) The LFR easy-mode bosses should really only drop iLvl appropriate BLUE items (I don't mind that the blue iLvl for t13 outstrips the Epic iLvl of t12). In addition, the artwork of the items (especially shoulder, helm, chest and weapons) as well as set-bonuses should be significantly different, even *shudder* inferior to those of the normal-mode and heroic-mode version. This shouldn't be that hard to implement and it would go a long way towards pleasing the different types of raiders equally.
Based on my interactions with other semi-hardcores/casuals, my experience has been that there will always be some poor people that invest too much of themselves into the game and therefore can't stand it for anyone else to have/see what they have. At the same time, there are just as many people who don't give a crap what other people do or don't see/obtain, as long as the content is challenging, engaging and interesting for them. It pains me to see the former group give the latter a bad name. It pains me further to hear people whine/moan about all 'hardcorish' players as if we were the same and as if we all hate the 'casuals'. We are NOT and we do NOT.
Take my guild for example, we have a group1 and a group2. Whilst group1 is the mega progression-centric group group2 was started to give the 'casuals', inexperienced, or simply worse players a chance at seeing the content. This group started in T11 and over the past few months they have grown and learnt as a team enough to reach 2/7hc this tier already. Hardcores and Casuals (and everyone in between) CAN mix. We don't need to hate each other and/or label each other to the extent that it becomes an "Us" v/s "Them" situation.

P.S. I was guild 2nd to hit 85 (the 2nd day after Cata released) but I am still a lore nut. I completed Loremaster pre-nerf and had Seeker a bare handful of quests into WotLK. I've read every WoW book there is (minus the anime/manga). Long story short, don't generalize about players in WoW, make you sound/look foolish.
