Gimmie wards. Even though there are areas of the map that are already granted vision (altars), these areas of vision a puny, tiny, and they have to be right ontop of it, and by then, the altar is already being capped and its too late. Jungling is also more difficult, one lane goes MIA and you're forced back to a turret or a teammate. You CAN play a champ with vision abilities (Maokai, Lux, Teemo, Shaco) but other than that, you're in the dark.
it's about playing bruisers, taking alters and derping around for 30 minutes while you get a full build before even remembering there are towers involved in this game.
With the lack of wards, this is so true. Often, you push to the turret, and end up getting in a 1v2 or 1v3 immediately, with no chance of escape. Even then, pushing turrets is usually the least of players worries when you got objectives to cap (especially some of the newer players, who never played TT and only tried it because of the update)
In short: wards were, they still are, and always will be an important part of competitive play.
