I got a lot of heat in in-game Chat when I 6☆'d my Megan recently. But you know what? Ever since I did, I haven't failed a Dragons B10 run (knock on wood) and before I was failing about 5-10% of my runs, depending on RNG and my team derping. Can I still fail a run? Sure, but the likelihood of that happening after 6 starring Megan is probably around the 1-2% range now. My point is, 6 star the monsters that are going to help your progression in this game the most. Don't let other people tell you what to 6 star or that you made a mistake 6 starring a certain unit. Take advice, but just as that. Because in most cases, as long as you've done the research and thought it out, you are the one who knows best on what's going to improve your gameplay. Had to rant a bit and share Don't regret 6'ing Megan one bit!
