MatthiasGaming: I felt like when he got bigger his personality changed, it almost became like a show/fake persona.
Arumba: Became a cranky unhappy person unfortunately..
A fewl (I don't want to give a platform): Became angry biggots:X
Jesse Cox/Pewdie Pie/Markiplier: outgrew the sense of humor/entertainment.
TLDR: Usually some change in personality alienated me.
Never underestimate the therapeutic power of actually doing nothing.
