...
we got some totally different art?
Somewhat, yes. a LOT of equipment artwork (armor, weapons, etc) was quite different than the original versions (Like war hammers, mauls, etc) , and in some cases had pieces that looked to be switched (ringmail leggings and either studded or leather leggings for a pair that was swapped).
After (at the time) 9+ years of familiaroty, people were annoyed at the new items.
Secondly several items had their perspective FIXED (fountains, dye tubs, etc), but again, familiarity trumped correctness.
Finally a lot of KR artwork, all that was really needed was a "cleanup" pass. Much of it got a LOT clearer as the Patchurdays came in KR so that in the end, there wasn't really all that much left that needed to be retweaked.
Of course was also post after post after post of outdated information, misinformation, and outright lies on the boards about the KR client.
Finally, the move and the change in dev teams delayed any further work on the KR client and ultimately led to the EC.
