well, for jungle right now, vision, and constant pinging helps. try to keep drakes warded when up, same with herald, and when you get a kill lets say with the team, ping them to help with the drake or whatever is up. Basically, you have to move the team as a unit through proper vision and timings, and if they follow, great, if they don't wait. If a lane is feeding, focus on other lanes, and I dont mean completely ignore the feeding lane, just tell them to play safe for a while. Try different routes out, be creative with that, for example, I go red, scuttle, gank if i can, next scuttle, blue, gromp etc etc. Figure out what works for you. Another tip, when a laner recalls, like, lets say mid, if the wave isnt pushed when hes at base, push the wave, hard push it, so it bounces back to him by the time he walks back to lane. Scuttles are high priority for vision, simple. Control ward first drake, get whatever drakes you can, all of them are good, the small buffs can make a big change, even if its not noticable. Help laner get towers when you can, like, lets say enemy top laner recalls, and you are near toplane, and lane is almost being pushed into enemy tower, go chip that tower if possible. Convert kills into objectives, you guys just killed enemy midlaner??? start herald or drake with numbers advantage of 4v5. ping ping ping. Never flame teammates, try to emote a lot to show you're chill, ask how they are in pregame lobby to get the good convos going, get the team communicating. Never flame. Ever. Try to be supportive with words. PRAISE your team when they do something good, it boosts their confidence and play. When they do bad, dont call them out, just say oh well, no problem, dont worry, etc. Wards are important as I already said, ask teammates to ward areas like rivers when you are opposite side of map. idk what else to say. try to get the team moving as a unit is what I usually do.
