I agree with Tim. Blade has a lot of good stuff in his time as staff, and I'm not against him getting a staff position in the future. Unfortunately this joke and the previous things with those other random japanese names were violations of the rules (no dual-accounts and pretending you're someone you're not) and drove some members to anxiety. In this regard he seems to have become used to having this power, losing touch with the fact that he can't just do crazy pranks just because he's an admin, and I think the best way to fix that would be for him to be a regular member again for a time.
I wasn't present when chase did whatever he did, but from what I've been told, he pretended he was a hacker and gave the forum a good scare. He was given a good thrashing for it. I fail to see how this prank is different, regardless if it was a post-April Fools thing.
I can't help but notice that all of the staff (Including me) were in a position to stop Blade if it got to that point. Other then those who were absent during the incident...
