Inadequate warding provided by supports.
One thing I realize playing jungle in silver elo is that basically, the wards provided by supports do not detect junglers at all to prevent ganks. They are just there with no meaning. Lux supports with over average 10 deaths per game pushing in and placing their trinkets in the river bush is one of these poor examples. Since you are using a immobile mage, warding the bush which is literally just right next to you means when you spotted a enemy mid/jung they already are on sitting on top of you. Even as Evelynn pre-6 I can gank your sorry ass.
This false sense of security by "warding the river bush" is so exploitable and meaningless within this mobility meta where you can either run past that bush in less than a second, or hop over it by a blast cone. If you are gonna push in, ward the jungle entrance so you can see enemies arriving 3 seconds prior they gank. Use creativity to assert your leverage and positioning.
