Upgrade Combo system aka Skillchains (Complex, system)

Thats something i really miss as a party experience. Nowadays, you can do your rotation alone without even looking at others members, its just you versus the fight. The skillchain system was easy enough to make people play together and attain a better group cohesion. It might limit in some ways too the spammy festival we're experiencing.

You would even fell more pressure on certains fights, like you have to wait for your BLM to get enough MP to unleash is powerful spells on the magic burst, but the timing is really short and the boss is about to launch a deadly spell...You proceed to start the skillchain, magic burst is enabled and pam, 1 second before the boss abilty, the BLM spell goes off and you win!

Well, thats the kind of stuff i'd like to see more emphasize, a real group play, not playing solo with 7 others people
