are we sure about the traveling differences? or an assumption? ALOT of ishy's early shennanigans were overly dramatic so it's possible that he just had an illusion added for effect.

is that the only instance we've seen true power traveling? or think we have? i recall a couple mentions of how fades traveling which is diff. and im rem'ing somehitng about "tearing a hole in the pattern", i think this was when moridin was the watcher draped in the warder cloth. maybe

i dont have any evidence against, or a reason either. but unless there's some more info im not rem'ing at the moment it still could go either way.

prolly right about ishy not using saidin anymore. he's as afraid of the link and it's corresponding "sickness" as osangar was of the effects on saidin around ebou dar. we see rand pushing on thru and dealing with it but ishy probably doesn't even touch it anymore, or else we'd see rand getting sick when he does.
