what i'm gathering is, they're buffing the colateral damage that will be caused by his ult, if he ults a back line target.
instead of just takeing the ultamite damage, if your not the target, it would give you a reason to activly want to dodge it, instead of just get knocked up for .75 seconds, and go back to killing.
example,(i've seen this happen), lets say the Titan of the deep ults a vayne, vayne is going to want to get away from the enemy team, so nauts ult has little effect on her getting killed, so she runs into the back line, through her front line, (why she was front line, no idea.). instead of just getting her team damaged a bit, and knocked up, she would now be jeprodizeing a whole team fight, becuase she didn't want to die. this change will give nautaluis, more things to work around, and to force the enemy team to accnolage his ult, rather than ignore it like you would a tank getting hit with CC.
the stagering blow changes, are just a slight power shift, since level 1, you'd interupt movement and have a 2 second cc chain, level 18, you'd have a 5 second CC chain if timed correctly.
might be to make up for the nerfs to Ap naut, but sliding over to a ap bruiser nautalius.
but what do i know, riot buffed nidalee, for some odd reason*[slayer-jinx-unamused]*
