Lissandra is a Solo Que dream
So I'm a real sick fuck. I'm that one mage player who plays Azir, Ryze and Viktor and can win lane but never end out the game. Really wanted to start climbing again and Viktor just wasn't gonna cut it after the Q nerfs. People suggested Lissandra and I've been playing her with her Aftershock build. Holy shit is she the best solo que champ for Midlane. A lot of people on here don't exactly know who it is that her Aftershock build is so broken or are just new. So let me explain why Lissandra is absuable until they really start directly nerfing her.
Free Ganks- Your role in lane isn't to poke, it's to give your jungler free ganks. This is especially true for when you are post six and have a point and click stun to go with the slows and root. Free Ganks could very easily also mean you being able to just E into a lane post 6, ult and give your ally a free kill.
I'm Not Aiming for the Kill- After laning phase is over and you start grouping you gotta keep this in mind, "I'm not aiming for the kill." What are you aiming to do after laning phase? Either ult the first priority person on their team in fights or E into their team, W and Ult yourself. This really isn't new, but you gotta remember what her new passive is. If an enemy dies near Lissandra while she is alive then they become a thrall and run at their teammates to AOE damage them. You aren't trying to kill anyone, you're just setting up kills for your allies. Your passive turns fights into your favor as they have to position away from the thrall that's running at them or else get hit but a blast of damage. You could even be in Zonyas and your passive wills till proc.
Dark Seal- Yeah, she can pretty much take this. It'll be a bit slower considering you're aiming more for assists than kills, but she's always gonna be able to stack it and have the AP she needs to do some damage. However, you must remember that Lissandra offers all CC. The damage is there, but that's not what makes her so good. You want a mage that's all damage? Go Zoe.
In conclusion, Lissandra is busted because she makes it easier for the rest of your team to carry. The amount of CC and presence she brings into fights with her ult and Zonyas makes her amazing. Aftershock is there as to make her survive longer as your passive only works as long as you are alive.
So yeah that's my little talk about Lissandra and why she's so good right now in solo que. Could you really take comet or even something like Dark Harvest? No. What the hell is wrong with you? Go Aftershock. Abuse your ult and passive.
