I agree that the game needs more interactive mechanics.. Not to bring FFXI into this, but weapon skills were always an interesting mechanic that I felt really made an otherwise bland combat system really dynamic. Mind you I'm not an endgame veteran of XI, but I see no reason why FFXIV can't own that CONCEPT and make it work within the parameters of the system they built. To clarify, I by no means want weapon skills to be directly translated, but an interactive component like that can be revised and reinvented as an "innovative" future mechanic.

On a quick glance I see no reason why the job specific skills can't be built in a similar manner. The CD's and the specificity of these skills would work well for limiting spam and it allows for job specific contribution to the party's composition.

EX.

Dragon Flare

BLM (Flare) + DRG (Dragon Fire Dive) = Deals a fire based attack that deals a burst attack with the potency of 500 following a successful combo, limited by a 300 sec recast. (Dragonfire Dive)

It's hardly brilliant, but these are the types of modest additions that I hope to see when pushing the game play forward in subsequent updates. It would be rather simple to implement with the current game, beyond balancing and recoding.
