Dominion was never the reason for the reduction of global teleport abilities. The addition of Nocturne to the game is probably most directly the event which brought global ults into view of the firing range. Against a team with global abilities your solo top lane was incredibly vulnerable because no amount of warding would protect you if you wanted to push the lane. If you overextended a 1v1 fight could without warning become a 1v3. Riot (generally) attempts to limit anything which promotes lane passivity, hence the changes.
