These patches track recommendation review, build validation and item lookup separately. Updating item data does not complete a build review.

A melee Bot route must survive ranged access before committing. Conqueror supports the longer entry while Barrier protects the close-range damage window.

BarrierAvoid duplicating the same defensive spell without a reason. Barrier protects the user; Heal can protect both nearby lane partners.
Choose Cleanse only when removable crowd control is the lane or fight problem and you can use it reliably.
Matchup notes
Track the cooldown and range of the ability that starts their safest trade. Do not treat this page as a statistical counter claim.
Treat Vex as one part of the map state. Their Jungler, nearby waves and which teammates can move determine whether the same trade or rotation is safe.

Judge the whole lane or map state, not only personal kills. Choose the situation closest to the current game.
Pressure farm with your Support while keeping the wave and river warded; two opponents can still punish an isolated carry.
Move after the wave is secured and attack the objective from a position your team can defend.
Deal damage to the closest safe target and preserve the shutdown. The lead matters only while you remain alive.
Match the opposing carry's income and trade when both lane partners can participate.
Finish the wave before rotating unless the fight is immediate and clearly reachable.
Stand behind allied control and build damage on reachable targets before stepping toward the back line.
Farm near tower or with nearby allies. Give up isolated minions instead of offering another kill.
Avoid being first into river and trade an unsafe objective for income when the team cannot contest.
Wait for enemy cooldowns and attack whoever enters your safe range; survival creates more damage than a desperate flank.
Pings, movement and objectives
Protect income and coordinate with Support. Your movement should follow the wave, while your pings make target choice and danger clear before the fight begins.
Pings create a shared plan; they do not replace checking waves, vision and who can move.
Finish safe farm and communicate the recall or move before the objective setup begins.
Walk with Support or another ally and choose the side where enemy engage cannot reach you first.
Keep an exit route and identify the nearest target you can damage without crossing enemy control.
Continue useful damage without chasing away from the objective or donating a shutdown.
Later objectives: Repeat the same process around later major objectives: handle nearby income, communicate the route, enter through vision and agree on the fight before committing.
