To be honest here is a copy of the conversation referring to the new Galio.
[10:39PM] Carlitos Danger: his ult is garbage it needs to follow his ally [10:40PM] Up The Ante: true [10:40PM] Carlitos Danger: not just go to where they were 4 seconds ago your basically counting on the enemy to be an idiot rather than trying to make a play off your own skill
I agree 100% should follow the ally to slam down to help them. 
ALL IN ALL NICE REWORK!
The point is to save a teammate, not knock up the whole enemy team. The idea is you drop a resistance buff on your ally then threaten their attackers with damage and a knock up if they don't get far away.
The knock up is supposed to be more of a deterrent than anything.
if they did that, theyd have to reduce the area by a large amount.
his ultimat eis very good
If they did that, he'd just be another Shen, which he already has bits and pieces of him and pantheon mixed in with the ult but it's not 100% the same. So, they did this, in order to keep the champions different.
