We need to talk about Kyrotechs

Almost every new marquee since when DR and Malak arrived (in 2019) requires 400 kyros to get to G13. There have been exceptions to the rule, with some marquees taking fewer kyros (IG11 and Kuiil only need 100 each, I think Resistance Heroes are 300 each) and some taking more (Armorer and Saw Gerrera need 500). This is not a new thing. We've all had 4 years to adjust. 

You get more kyros thank you think. We have 8 Assault Battles that award 20 kyros, that's 160. You get 3 each day from the daily feats box, that's another 90. Then we have kyro drops from TB end rewards + what you can buy for GET2/3 + Zeffo and Mandalore boxes. 

I geared up the 4 gungan marquees from zero to G13 in July to qualify for JJB in August. Thst's 1600 kyros right there. I rarely ever buy kyros for crystals (usually if I have a toon at G12 just waiting for some kyros to hit G13, I'll spend 700 crystals to buy 25 pieces). The majority of my kyros come from events and TB currency and I can usually gear up 3 or 4 post-DR marquees in a month. 

Just Zeffo and Mandalore (assuming you get both boxes on each planet in each TB) get you 140 kyros per TB, so 280 a month. 

That doesn't account for kyros you can farm up with regular energy. Even if it's 1-3 a day, it adds up over time. 

Your problem is bad resource management in a resource management game.
