Champions such as Twisted Fate and Rengar can provide global or ranged vision for their team with just their ultimate. New TT was made so that both teams weren't able to buy wards or know where the other team was on the map all the time. Sure, a moderate version of Wriggle's Lantern was made to reveal an area, but it is only temporary.
To me, it is very easy to get aces on there every time when there was a Rengar on my team and with the right team composition, it is easy to control the map if you had the right champions for it. My entire team would wait in the brush, Rengar pops his ulti, and it reveals champions for a few seconds. It isn't global, but it is great utility, huge range, and a great initiator.
