Renekton

Ruthless Predator (W) stun needs melee contact and Slice and Dice (E) is a short dash, not a real gap-closer. Akali stays at Five Point Strike (Q) kunai range, walks Twilight Shroud (W) on the commit frame, and roams the moment her wave is shoved.

Without a long dash Renekton walks 700 units through Miasma (W) and Noxious Blast (Q) poison to reach her. Twin Fang (E) sustains back to full HP every trade and Petrifying Gaze (R) stuns Ruthless Predator (W) lockdown.

Carnivore (P) sustain matches Cull the Meek (Q) heal in trades, and Rupture (Q) knockup interrupts Slice and Dice (E) stun dash mid-flight. Feast (R) executes Renekton below the stack threshold once Vorpal Spikes (E) burn chips him down.

Fiora's Riposte W parries empowered Ruthless Predator stun outright, reflecting the stun back onto Renekton and cancelling his all-in commit. Duelist's Dance vitals deal true damage every few seconds, ignoring Renekton's bruiser build,

Decisive Strike (Q) silence interrupts Ruthless Predator (W) stun cast before fury empowers it; Courage (W) active eats the Cull the Meek (Q) heal-trade burst. Without Garen committing autos his fury bar stalls and Dominus (R) is the only late answer.

Ruthless Predator (W) stun requires staying inside Harsh Lesson (W) leap range; Slice and Dice (E) dash-in plus dash-out leaves him committed when Test of Spirit (E) lands. Dominus (R) HP swing cannot match the Tentacle DPS during the Leap of Faith (R) window.

Slice and Dice (E) double dash burns into Path Maker (W) stun on the return — once Renekton spends Ruthless Predator (W) stun, Ntofo Strikes (Q) 2-stack detonation locks him in place. All Out (R) burst phase eats through Cull the Meek (Q) fury sustain.

Renekton beats Morde levels 1-5 with Cull the Meek (Q) sustain and Dominus stun, but his kit has no answer to Realm of Death (R) post-6: a clean R off the wave isolates him from his team and Mordekaiser wins the 1v1 with stolen stats.

Quinn sits outside Ruthless Predator range and chips Renekton's HP for free with Harrier passive auto procs. He has only Slice and Dice double-dash to close — once it is on cooldown, he eats Blinding Assault poke without any way to retaliate,

Slice and Dice (E) covers ~400 units of dash and Cull the Meek (Q) is melee-only — both fall short of Ryze's 1000-range Overload (Q) poke. Stack mana with Doran's Ring while kiting his Ruthless Predator (W) stun, and the Rod of Ages spike out-trades his fury-bar burst window.

Cull the Meek (Q) heal stalls vs Shen because Twilight Assault (Q) max-HP damage shreds him faster than he heals. Shadow Dash (E) interrupts Slice and Dice (E) re-cast windows, and Spirit's Refuge (W) blanks Ruthless Predator (W) empowered stun-auto.

Renekton needs Slice and Dice (E) double-dash to commit and Cull the Meek (Q) heal stalls on a stacked Sion HP pool. Soul Furnace (W) shield eats the Ruthless Predator (W) stun trade, and Decimating Smash (Q) charge interrupts the Slice and Dice (E) re-cast window.

Renekton's Slice and Dice E plus Ruthless Predator W stun burst is short-windowed Fury-gated trade damage. Each hit feeds Tahm's Thick Skin grey-health bar, the 3-stack Tongue Lash stun catches him mid Dominus R Fury regen,

Teemo sits outside Ruthless Predator range and chips Renekton's HP for free with Toxic Shot poison. Blinding Dart denies the Reign of Anger Fury auto-build, and Move Quick speed kites Slice and Dice double-dash range.

Renekton's Dominus R Fury regen burst expires inside Undying Rage's 5-second 1 HP window. Slice and Dice E double-dash cannot escape Tryndamere's Spinning Slash E chase, Ruthless Predator W point-click stun lands during the immunity for zero damage,

Vayne sits outside Ruthless Predator range and chips Renekton's HP with Silver Bolts true-damage every three autos. Tumble blink repositions out of Slice and Dice E double-dash range, and Condemn knockback flings Renekton into the rear of his own minion line,
