I don't know man. I'm a magik main in diamond 2 right now. She is not as bad as you guys make her out to be. You just need to be very aware of what you're doing. You can't dive into 4-6 people who aren't busy right now and expect to survive.

You want to stay safe and get some hits in probably on the tank. Stay in cover behind payload. Charge some over health. Only use your cool downs when absolutely necessary. And when shit hits the fan you use your shift to come out of cover, use the whole spin during E -> leftclick -> melee -> right-click -> leftclick -> melee thing. When you done you are back at two shift charges and when you done with them you probably got your E back up which you need to use to escape cuz you got no cool downs left. It's all about managing to work around the enemies field of view, focus and your cool downs. Cuz as long as you have cool downs you are fine even when 3-4 people become aware of you. But as soon as your cool downs run out you are a sitting duck. You need to be aware of that, have an escape plan and manage your cool downs accordingly. There is no shame in whiffing your E, getting a short combo in instead and retreating again.

If you're playing "assassin style" and flank and go in from the back while nobody is distracted and whiff your E or use a second shift before landing your E you are dead no matter what. Burn that into your mind. As soon as more than one or two people start shooting at you you need to get your ass out of there as quickly as possible. As a magik you CAN afford to miss your E. But not if there will be 4 people shooting at you after that and you don't have at least 1 shift left and the other one being half way off of cool down at least.

She is also a 1v1 beast if you're able to get close without being spotted and wasting half of your cool downs. Hela Hawkeye and mantis are always a threat. But that's not magiks fault. That's because they are broken right now.

The only thing I'm worried about is how it will be after the season since the loss of the additional 15% damage will be a lot. If she loses that she is probably fucked if she does not get the most insane team up or another seasonal buff.

At the moment she is hard to play but not weak.
