I like Titanis but only because of her one trick pony Dex Pixia.. the rest of her rework was terrible, honestly there seems to be a disconnect with how skills are on paper with how they perform in game.. Titanias 1, 2, 3 are really quite useless from trying them..
I guess the high level power creep just made so many frames skills pointless and to be frank useless.. they need to tone down the 80+ content as it makes the frames not work.
Nyx while ok i've not found her rework to be all that fruitful, she feels even worse imo than she was before the rework.. her number 2 needs to just be spammable. And her number 4 should let her move around without the augment..
Nyx needs more health or more armor by default.
