Not at all a problem.
TBH i see no prbolem with a raid which can not fit in regular 10 or 25 man guild schedule. So what if there's a raid which is optional and is not intended to be something you do ONLY with your static raid or guild?
For example, Galleon, as it is now = optional, for those who do not mind spending days and weeks searching for him, who don't mind all the lags with like 400 ppl gathering at respawn point when time comes. I've only killed him once, but i don't cry that some others kill him every CD.
What we REALLY need in wow is a 3-day lockout raid like ZA, wich does not really fit into what we do with our guilds. Failed your lockout with some noobs? not a big deal, wait 3 days and find others.
The same goes for 40 ppl raid
I don't mind larger (Not AQ40 size, I hate it taking 5 minutes to run from the entrance to end while mounted) as long as they don't make it inconvenient like HoF or MSV. If the time it takes to walk from one encounter area to the next is more than 20-30 seconds then I don't like it, it feels like a chore then and just bores me (I make lots of mistakes when bored so it rather sucks if the layout of the raid itself bores me).
ToT looks pretty massive. Just the cave area alone where Megaera is looks enormous.
Heart of fear and similar places "look" cool, but they're just kind of... there. They have no meaningful props, no chambers, no "rooms"... Bastion of Twilight, Tempest keep, and almost all of the Burning Crusade dungeons had this same problem. Just empty hallways and giant empty boss fight rooms.
I also think it's important to make the raids non-linear. Make each "wing" feel diverse from the other. If blizzard were to indeed go back to "giant" raids, they shouldn't all be "inside" with one "on a balcony" thing... they should have massive outdoor sections, and diversified indoor sections as well.

Just did kara for the first time a couple weeks back and NO, just no.
Way to big, and doesn't create more of an epic feeling, i thought icc was way cooler
Honestly, I wouldnt mind a big raid as long as there will be teleportations to other wings and not as many trash as say, AQ40 or Ulduar.
