I disagree with the OP. There are many skills that can be used very effectively in different situations other than just doing combos over and over. Doing combos is the best way to do great dmg, but a lot of these end-game fights are not dd races. The DoW players, for example, that feel they HAVE to do combos on the ifrit fight end up dying or getting other people in the party killed. The archers that just use shadowbind on the moogle that's being killed during the moogle fight to do more dmg are the bad archers. Use shadowbind to bind the moogles that are on the mages. You can split combos between mobs. Not making smart decisions with your skills are your flaws.

I'm seeing threads on these forums about how some skills are useless like resonance and sanguine rite. Resonance is amazing for situations where you have to run away from the tank such as during eruptions in the ifrit fight.

I think this battle system is a lot better than the one before 1.20. I do agree it's not complete, but no one said it was. All these changes are parts of a bigger picture. I'm looking forward to the additions of jobs and battle regimen to make the battle system even more interesting.
