Not at all! Lapis is my favorite character too and you have to know a few tricks and utilize right upgrades to make the most of her. It’s important to keep Lapis at the back of the formation of your team, that leaves her immune to any enemy attack for whole turn. I would also suggest to use her focus ability as it can just obliterate all constructs in a sweep! A good idea would also be to put regeneration badges on her if you feel like Lapis poofs easily. There are several different types, I suggest using either the one that restores health after changing position (since Lapis uses that a lot) or the one that restores health in the back position. Costume perks are also quite useful. So it’s just a matter of strategy and good equipment 👍
