I think most of the people didn't like the new cards system

Here is my suggestion:

Add 1 2 3 combo that will trigger 4 that will switch each 123 to cards

Card 1: increase single hit damage for party member
Card 2: increase damage for each GCD for party member( jobs like black mage will benefit more)
Card 3: increase damage for each GCD + OGCD for party member( better for jobs that cast alot of ogcds like gunbreaker)

4 which is "play card" will have 60 sec cooldown and switch to damage AoE attack or AoE heal depend each time it been used.

Let me know your opinion
