I imagine that the text would be flooded if overused, but perhaps a DM can set it on items as a reward for casting PCs. There is already a lot of text spam in chat and larger events, and I think that the emotes should be saved for dramatic moments or used every once in a while.
Imagine buffing for an event where just one person may be casting multiples of the same spell. For example casting bull strength:
[Muscular arms weave crimson magics over their companion]
[Muscular arms weave crimson magics over their companion]
[Muscular arms weave crimson magics over their companion]
[Muscular arms weave crimson magics over their companion]
Items that provide colored text when players cast certain spells -is- cool though and I am sure people would be jealous!
