Air req 175 is quite high for a low QL yalm ...I'm level 34 and I have 200k+ credits. Only once did I ever ask for money and that was from my clan. The reason? Well there was this nice Yalm that had a air req. of only 175
Thanks to the IS passes, I made like 30M credits. And guess what ... I was not selling them for 1M+ each but for 300k each or 1M per bundle of 4.
Those passes created a lot of overgreedy low level doods.
Shameless ad : I still have 12 passes for sale, for the same price as above (still best deal on Rubi Ka 1)
