Laurel Lance is by far my least favorite character in the arrowverse and here is why
1. She vastly overestimates her importance to the team.
2. She thinks she is capable of taking on foes that aren't street thugs, she tried to fight the league of assassins, Malcolm Merlyn,and Damien Dhark.
3. She acts like she can do whatever she wants and acts like she is the boss of Oliver
4. She gets mad at Oliver for not training her
5. She Pathetically tries to take up her sisters mantle
6. Even after being trained by Nyssa Al Ghul she still cant hold her own
7. When everyone told her not to she still put on her sister's mask because she is a helpless wannabe with no training who got beat up by a random unarmed dude on the street
8. She demanded Malcom Merlyn to bring back her sister as if she could do anything to him, she said "You took her life, you have the obligation to bring her back"
9. She brought Sara back to life due to her own selfish desires even when Malcolm and Nyssa said not to, the only reason Malcolm did was to clear his daughters' guilt.
Earth-2 Laurel is better in every way possible than Earth-1
