After 14 weeks I have finally finished farming the first set of old republic toons and now ready for Revan! I made a gif of screenshots showing the progression. My strategy was to focus farm one hard and ship node toon at a time and one cantina toon. Started with bastilla and T3, then jolee and mission, and finally zaalbar. I refreshed cantina nodes 1-3 times per day and bought all 600 cantina energy packs. Phew! Ready for old republic round 2!
