When someone starts a reply with "it's very easy", I am not inclined to listen much further. I never said they were hard. I said the telegraphs are badly designed. I've run it multiple times after the first run and didn't get hit by anything. I understand how the mechanic works: the way I deal with it is by not paying attention to the second cleave since it's always a thinner cone of safety directly opposite to the first one, so the only one that matters is the third one which can be left or right compared to the first two. It's still grossly guestimating boundaries though due to the lack of visual feedback on where things clearly end.
