See, I'm going to have to strongly disagree with this. AE has amazing synergy with our other arts, and here is why.
TRF, AC, FZ all have passives that are supported by having allies around us to benefit. The whole point of those specific arts is to have allies that can capitalize on the additional passives and techniques to make them last longer, hit harder, and move further. AE is the only art in our entire arsenal that can make those allies from our qi. Upon formation, these minions have more physical defense, physical attack, ranged defense, and movement speed then they should.
Furthermore, our entire build is based around an attrition style build that debuffs the enemy into impotency. We weaken their offensive capabilities while crushing their defensive capabilities. This allows much weaker allies to actually be useful in a fight by allowing them to hit and deal damage rather than just be meat bags to wail on.
Speaking of meat bags to wail on, the minions summoned by AE also serve that purpose, especially once we have things set up to create our zones of death. Ling Qi has an absurd amount of qi, and that amount will continue to grow as we use the Sable Light Pills. Utilizing that qi to make the opponent spend action points killing the summons gives us time to keep stacking the defense buffs while waiting for our attrition style to whittle them down.
That's just one technique. The other technique provides a multi-attacker penalty and armor degradation, all without having to actually hit. I will admit, it will be difficult for that technique to hit and provide the -2 defense and 2 qi drain, but with all of our other debuffs, it is possible.
