You need at least 40.000 feet at all times with full load.
33.000 feet empty isn't enough in mountaneous Kandil area even against PKK MANPADs,
neither is the speed against turbojet missiles of Iran
and neither is the self protection capability and situational awareness against radars of updated Russian SHORADS as we have seen in Ukraine.
TB2-3 can't handle new capabilities of PKK, so how are they going to justify their cost, especially against Greek F-35s and Patriots?
Ukraine has billions of dollars aid but they didn't ask to buy single TB2 from Baykar, since they don't last even 1 day now.
