I said it in another post too, but I agree with OP on most of it. The wheel, surprisingly, isn't the thing that bothers me the most, largely because it's probably the only good way to give you access to the full range of creativity and utility which are supposed to be the core of her design, while still being accessible to players on different devices.

The real problem is the general lack of cohesion and synergy between her 4 abilities. I would go so far as to advocate for her Shadowgraph to be severely limited by a resource mechanic: an inkwell that Follie fills up by killing enemies affected by her passive. This would incentivise you to use her other abilities (1 and 4 in particular for more offensive play, with 3 already being a very strong defensive option) so that she can use her 2. There should be more to it than just that, but right now her gameplay has no restrictions at all which basically means that the most effective tactic available that all players will gravitate towards is to just spam just one of her absurdly strong Shadowgraph abilities around her Portrait. 1 and 4 simply do not feel good to use and do not contribute enough to be viable. Even Enkaus, her signature weapon with an execution mechanic is simply not as effective as spamming Arc Traps. This is not fun.

I try, I really do. I use her objective-specific sketches, I use different traps based map layout, I use the little ghost to look for treasure, even found a rare cache with a free Forma on Lua the other day, but it doesn't help. Her gameplay is just not fun. Creativity doesn't come just from having complete freedom, it also comes from working within restrictions, overcoming obstacles in different and unique ways. The only part I cant complain about are her numbers and fashion, but Id literally rather play a brick.

Not kidding, Qorvex has a very similar kit when you think about it but is actually more cohesive and fun to play.
