How to play Lissandra effectively to her strengths?
I like Lissandra's story, and recently got Program Lissandra from a chest. Played her again, she does require some finesse. Champion.GG doesn't fill me with a lot of confidence, but as I recall the last thing she received was a nerf to her health per level for being too tanky among burst mages. (Actually I had to look up what the actual reason for the nerf was, I didn't remember it.)
From that I gather she should be in an OK spot even if her stats look atrocious. What are the secrets to playing Lissandra effectively? Itemisation-wise, I tend to go for Morellos, but I'm starting to feel like I'm making the wrong itemisation choices and building her like a Lux or Viktor.
Should I grab Hextech Protobelt and Rod of Ages?
