I too have 313/317 & beaten everything excepting Jaral. I feel like I gave wasted the weeks playing. Do the makers not want me to play their other games?
Finished with 4 stars, all missions excepting Jaral. The last one took 3 tries with Felmor, T'lanac, Narghal & Kassia. That team is my best but still the guardian to Jaral prevent me from more than 314/317 stars. Darn Jaral is blocked.
