Yep, we don't really give a damn what Blizz chooses to call it. What we want is something to do in between patches other than sit around waiting for next tier. Give us something after normal that offers a challenge for us while the most elitist of the elite go and do what ever they want in Mythic. Making "Normal" so hard that the majority of guilds cant complete it before the next patch hit would not work. It flies pretty directly in the face of everything Blizz has done with regards to people seeing content.
I feel I need to reiterate that just because a guild doesn't down all content on heroic doesn't mean they should automatically be excluded from trying. It is genuinely very good fun to go and attempt these fights even knowing you might not get all the way up to the last boss.
The challenge offered from downing AND attempting current Heroic content, combined with having fun with mates over skype etc is what is going to be taken away from a great many 10 man guilds next expansion.
I see what you're saying, maybe Blizz will take the middle ground a bit with tuning and make Normal kind of halfway between Flex and Normal, and new Heroic halfway between current normal and heroic, so that it can continue to present a challenge for almost all groups until the end of the tier. Also, and I'm not saying they should, if they made entering heroic require clearing normal that would make it seem like flex was just gone, they made normal and heroic both flexible but scaled each down somewhat, and added a new tier above and beyond heroic that most groups wouldn't reach anyway unless it was their purpose to get there...
hmmm, if only.
I can't speak for the rest of the 10 mans out there (and the 25s who feel they are affected too) but personally, and I think from my guilds perspective, that is the ideal solution to this situation. =D
