Yeah. By the time of the murder mystery, DDA was a close rival, and I think any other guild was far behind those big two. We don't really have much info on the state of the clearing guilds by the time of the 75th floor. I get the impression that the rivalries had faded somewhat, as the number of active clearers steadily dropped. I would think the scouting party they lost was a mixed group, for example.
If we trust the anime on this, by the time of the 75th floor, no guild is really dominant anymore aside from KoB using Heathcliff to tank and Asuna to plan. It looks like boss battle tactics have long since set aside guild pride, and everyone just sends only their strongest; KoB only has 3 known members in that fight in the book version, more like 6 in the anime; Klein is the only member of his guild present; and in the anime I only noticed 3 members of the DDA there. (I saw Schmitt there!).
Progressive could easily revise the player strength situation using things that showed up in later books, of course. In book 1, only the clearers were strong. In book 2, sparring matches in safe zones were mentioned. By book 6, some more safe training mentions were mentioned (Kirito, Asuna, Klein and the gang did advanced hide and seek, XaXa had continued practicing while in prison). By book 8, there were a bunch of player-run dojo in ALO. It's not hard to imagine a mass effort in old Aincrad to find ways for the clearers to safely train up lower level characters in both actual system skills and essential outside system techniques.
