I agree with many people that say gear tokens should be broughht back in the operations (or at he very least gear drops, e.g. chest, MH, legs, etc.). That would make gearing much faster and much easier. Also, a legacy wide GCP system would help alot advancing through the 300 GC ranks for all the characters. I just hope eventually they will follow this route. Maybe they could also add T1 (1-90 GC rank), T2 (91-180 GC rank) and T3 (181-300 GC rank) vendors.
Well, this might be a good start.
These are some good ideas.
