Fixing Kai Leng

The problem with Kai Leng is Mac Walters desperately tried to convince us that Leng was Shepard's ultimate equal when he could barely hold his own against an aged Anderson and a Drell with terminal cancer and in the end he was a tryhard egdelord that would make Kylo Ren embarrassed.

The solution to this is make Leng deeply connected to Shepard's personal history. Making him be a ghost from Shepard's past with a personal connection would have made this character much better. His backstory could change with whatever your selections are for Shepard.
