I feel like the issues with Titania aren't really being addressed
Right now her biggest strengths are in razorwing (mostly for boss fights like sortie Lephantis, and also for it's mobility on the plains with augment) and her bullet jump passive.
Her energy pool is small despite being a warframe who's meant to constantly cast all her powers on enemies, along with long cast animations that take two-hands to use.
Her 1 and 3 are both cc and compete with each other for utility. Her 1 alone has this weird "it makes enemies float, but it also disarms them" which means no one ever notices (or even knows) it has a disarming effect because it is two cc effects competing.
her 2 isn't just the fact that it's something to spam, but that the buffs it provides just aren't good. Like all of them are kind of just mediocre in utility. Also the thorns still falls behind the issue of "enemy power levels aren't equal in offense/defense making damage reflection generally bad". In fact that's kind of why Nyx was getting her rework.
