So unbalanced!!

Why would your squad mates lose ALL THE XPs when they die??! Thats so unfair, especially since I saved up thousands of XPs to unlock a trait!! And why would traits cost so much XPs??! Are there no other (faster) ways to get XPs?? This only encourages the player to spend XPs as soon as theyre gained and thats simply poor design!
