Giving Illusionist Telepathy was badly needed as otherwise if Psychic was converted he was immediately caught. As was removing Visions, as they did not belong in a social class anyway - Psychic often found more scum than Observer.
Before last Patch Psychic was OP, but I think he was very well balanced after it. With this most recent patch playing Psychic will just be infuriating - literally no one will give any info to you in an Unseen game, and Scum have a great excuse not to try and fake claim to you.
I think they should make linked minds a limited use ability on the Illusionist and replace mental blur with a main night ability. As it is Illusionist has gone from by far the best BD role to one of the worst.
