If anything, junglers got a major buff. The new Utility tree gives 422 starting movespeed with boots, which also opens up more starting options. Jungle clears are faster in general, even when taking into account the new wight camp, and junglers can buy better items earlier, which would compensate for the general increase in wards. In the early levels, though, trinket wards don't actually last that long, and so give junglers a 1 minute window where they can gank every 2 minutes.
