I quite like Chuchu, he's a fun boss. I'd really prefer it if people would stick together a bit, so I could use Eos to her full extent, but can't have everything. Sure, the first time you fight him it can be a bit iffy, especially if you get barfed on. Thankfully, lustrate+fairy+leeches solves that.

I think it's a wanting to learn issue. I'll give my sister as example; she's casually leveling a ninja. She's enjoying the game but doesn't play all that often. Recently we went into Stone Vigil, which is the first instance (afaik) that uses moves without orange markers. The first boss does that 'run to the wall and breathe on the room' thing, the last boss does a stomp or something. It's not hard, but she got hit by them so I told her to use /focustarget to keep track of boss HP/castbars. Her reply was 'Nah, that's too much effort. I don't play that much anyway.'. I'm now a sad sister. I'm also worried about how she'll ever deal with Coincounter.
