Truth to be told, gearing a job from scratch can take some time in 2.4. As someone pointed out, things should be easier in 2.5.
Now, Crystal Tower 2 is still a good place for getting ilvl 100 gear and tokens used to improve martial equipment. On the other hand, we are talking about a 40min raid.
T6 and T7 are great opportunities to get i110 stuff, and once again tokens. But whereas you can enter CT2 with a weak equipment, this is not the case for these, and despite being nerfed the party still need to know the strategy perfectly to avoid wipes (not to mention you have to down T5 beforehand). On the subject of T1 to T5, T1 and T2 became so easy it would be a mistake to not farm those if you still need ilvl 90 gear. Caduceus is a joke now.
