Keep Vex visible before committing. The second Bot-lane champion and nearby Jungler can change whether the same engage is safe.

Jarvan's first basic attack on an enemy deals bonus physical damage based on their current Health. This effect cannot occur again on the same enemy for a few seconds.
Jarvan IV extends his lance, dealing physical damage and lowering the Armor of enemies in its path. Additionally, this will pull Jarvan to his Demacian Standard, knocking up enemies in his path.

Judge the whole lane or map state, not only personal kills. Choose the situation closest to the current game.
Deny space with your lane partner, but keep the carry connected to the wave instead of roaming at every opportunity.
Move first with an ally, establish vision and protect the route your team will use to enter.
Start only when allies can follow, then change to peel if an enemy reaches the protected carry.
Hold the ability that makes opponents respect your lane and trade when both Bot-lane partners are ready.
Recall and move on safe wave timings; an unsupported roam can cost the carry an entire wave or a dive.
Control one approach and keep enough protection for the enemy's most likely engage.
Stay for a crashing wave, block a dive and avoid spending the key defensive ability on low-value poke.
Enter darkness with another player and ward the nearest useful entrance instead of reaching for deep vision.
Peel first and punish overextension. A blind engage rarely repairs a losing game.
Pings, movement and objectives
Turn information into a shared decision. Move with an ally and preserve the tool that makes the next fight safe.
Pings create a shared plan; they do not replace checking waves, vision and who can move.
Around a minute before Dragon, ping the plan, spend gold if needed and make sure Bot and Mid know whether they can move.
Walk with the Jungler or another ally. Sweep one route, place useful entrance vision and never face-check alone.
Check nearby waves and enemy positions. Hold the spell that either starts a reachable fight or protects your main damage dealer.
Keep enemies away from the safe entrance, mark the reachable threat and avoid chasing so far that Dragon is left unprotected.
Later objectives: Use the same pattern for Rift Herald or Baron: communicate first, move through controlled vision with an ally, then choose engage or peel before the fight begins.
