Nothing wrong with good 3 class armor so long as there is good in between pieces that cater to individual jobs.

Example. Everything new for mages is useless to well geared RDMs. Absolutely nothing good. But you give us a couple of transitional pieces and we shut up. See Morrigan's +1 for why our nuking and WS sets are fine. The only thing we are lacking is good TP pieces.

Same thing with healing magic. We don't have a healing magic set as part of AF or a specific gear set, but we have access to what we need and then some.

SE needs to keep making pieces that are specifically good for very specific jobs to keep people interested in what their job has for them, but by no means do they need to slow down good 3 class armor. It takes care of about 75% of our gear and gives it to everyone in a fair manner. All the heavy's have access to the same base heavy gear, light for light, mage for mage.

The only big exception is pet jobs. There is no pet job armor so every pet job has to sift through gear to find things that are actually relevant to their job.
