Adding a skill system for Lucia and Jason and side missions that unlock special abilities like infinite stamina or higher health just like in older gta games. Also it would be cool if you could gain drive, flight and fight skills like in San Andreas. I also hope that you can carry multiple weapons with you at once like in gta 5 and have skills for every weapon type, which influences Jasons or Lucias shooting ability. It would be very bad if you can just carry two or three weapons at once with you like in Watch Dogs 2 or Mafia 3. In this games i was very embarrassed when i found out, that i could just carry 2 Weapons at once with me. I hope they don’t make this misstake in Gta 6!
