No what hes getting at is that in this xpac engineers need alot of violent air, ALOT but the system for harvesting the required air is very inefficiant at obtaining the air and people are spamming them as individual units for 50-100g each blizz added the gizmo that supposedly boosts engineers harvest rate but it doesnt even fit in engineers bags and doesnt boost the rate to anything even remotely economical, in short they need to go back to the system like the crystalised elements where thry were redily avalible through engineer specific devices and could be farmed sepratly without mining
