Tanaka was wrong. Disagreements happen, and from conflict comes resolution. Most people will argue their side solely, even if they do see the merits of the other viewpoint. This is how arguments work. Arguing is good.
Personally, I like the changes because combat is currently broken. Sure, it's much better than it was 6 months ago, but it's still broken. Combat changes have been good so far, so I'm going to continue my present optimistic attitude toward changes until I see a reason not to. I have a hard time with people who are upset about the solidification of roles, as there has been plenty of information regarding the roles the different classes will fill. There has been time to change course and modify your expectations.
As for soloing... it doesn't look broken to me. Every class, with the exception of Gladiator, appears to retain solo ability. I could be wrong here, but if you think there's a class that has lost solo ability based on these ability lists, please say which one, and I will gladly explain how I think you're mistaken. As for Gladiator... well, see the next paragraph.
We have been told there will be 15 abilities per class at level 50. Given the fact that other than the DoMs, each class has less than 10 abilities listed, it is safe to assume that these lists are not complete. I imagine that the remaining abilities will fill in some of the gaps that the current list leaves open. This intent of this list seems to be to clarify roles. I'm sure the unlisted abilities will address things such as Gladiator's solo ability and LNC's complete loss of utility. Of course, this is just speculation, other than the fact that these lists are not complete (that is clear).
EDIT: Belay my last paragraph. My count is thrown off because of the funky indentations on comboed WSs. After recounting, each list seems complete. My apologies. It does seem that soloing as Gladiator will be painfully slow. Here's hoping that something can be done about that.
