Scrapper had an F skill replaced and a minor trait given a buff/nerf. And I would argue the balance team took the same approach with distortion and alacrity. Our version of losing vitality to gain barrier is losing IP to keep the benefit of alacrity. However, since raids are the only game mode with long/predictable fights, all the tradeoff does is devalue Chrono in the rest of the game.
My idea would be to reduce the max number of illusions and restore illusionary persona. But I am sure there are better ones. Any other ideas?
