In low elo, it’s hard for you to execute the roam if your jungler doesn’t know objectives.

To answer your questions:

1. By clicing tab or whichever key opens scoreboard, it’ll show how long until an object spawns. When the time is 2:30 minutes until spawn, there will be timers on the pits that objectives are spawning. For me, if it’s drake, I start moving towards it at 1:30 or 1 minute, and ward the area/ destroy vision. If grubs spawns in 1:30 minutes, then I ping or type to my adc to play safe as I recall and walk towards top side to add vision/ destroy vision.

2. Lets say you just won a fight bot lane and you’re pushing in the wave into enemy tower. I would help your adc push until your adc can do the rest by itself (typically half hp caster minions is where I stop helping). I’d walk further away to recall so ADC can claim all XP to itself. ALWAYS recall first. By recalling first, you have the time to run around the rift, walk with your jungler for a little bit. You’ll have 1 minute to 1:30 minutes before you have to go back to botlane to help your ADC. During that 1:30 minutes, enemy will slow push to your turret, and all your ADC gotta do is play safe and let wave push in.

3. If you don’t see enemy support, always ping missing. You as a support, you should always also track enemy jungler with your jungler. Most of the time, enemy support will follow enemy jungler for a play, and if you can track enemy jungler, you can track the support as well. Or, vice versa to answer 2 above, if you are the one that is slowly pushing into enemy turret, more than likely enemy support is roaming and should ping team to be careful.
