the biggest issue is the procs, period. since JA works so much better than the others that's where you will find the soloers. and in fact you'll be lucky to find any non melee jobs /dnc at all. I've especially never understood the argument against magic procs. yes, you can spam spells faster than ja. now, with the exception of blu and nin look who you have spamming spells. you may notice a theme of jobs that take a hit about as well as Lindsey Lohan takes a sobriety test; yes, I know pld and drk, but both have limited MP pools so it's not that much of an issue, and even nin it's pretty hard on the wallet to spam magic.

Honestly, the most positive change they could do is to adjust procs to open up the other 2/3 of the mobs. The fact that player X can come rdm to solo again would just be a bonus. Wait, it would make rdm a viable job choice, I'm wasting my time, forget I said anything...
