My guild is pretty casual, majority of us got to 70 level last reset so my guild missed the first raid ID. People claimed TBC to be time consuming for raiders but I'm not seeing what is the time consuming part or am I missing something? We cleared Kara + 25mans mostly with dungeon blues and some of us had tier 3 gear so we have already secured T4 clear even tho Magtheridon took us one whole night.
The only faction I'm revered with is the Cenarion Expedition and I still need the Honor Hold rep to summon Nightbane but it wouldn't take that long if I only wanted to finish that. Guildmates can summon the Nightbane and HC instance / badge loot is not attractive enough to care about grinding them since I'll get gear from raid eventually. I'll get revered slowly but surely before Tempest Keep / SSC launches (for attunements) so reputations arent the time consuming part.
Consumables are cheap so I can't think any of "time consuming" part necessary for raiding. I'm ready for raid logging as casual unless I'm missing something? I think we'll get almost full T4 before T5 releases so gear shouldn't be a problem with raid logging.
