We’re in a new era of Wizard101 going forward with better quality content. Many of the original spells are a bit outdated in terms of quality texture. I really like what KingsIsle did with updates to mobs around Wizard city. Specially the new Kraken looks amazing. Bringing that same concept to improve old spells will be another step forward. The creativity behind it, better quality in visual effects, textures, and sound.
I totally agree and have thought of this! Maybe after the next world they will have time/before developing next world to focus a lot of energy onto re-textures. The spell quality can also be tog-gable from "Classic" to "Modern". I think releasing the texture updates in waves such as starting with 1 pip spells in an update, maybe a few months later 2 pip, just to slowly improve the game while being able to focus on big projects!
