“Just stack bro” — the most common climbing advice in Siege, and it’s incomplete. Stacking raises your win probability but costs you RP efficiency. Solo queue gives full RP per win but subjects you to teammate roulette. The real question isn’t which is better — it’s which is better for you, right now.
This guide breaks down the honest trade-off for every queue size: solo, duo, trio, 4-stack, and 5-stack.
The Core Trade-Off
Two forces pull in opposite directions:
Coordination (favors stacking): comms, trades, executes, no throwers. More coordination → higher win rate.
RP efficiency (favors small queues): 5-stacks face a squad RP penalty and tougher lobbies. Fewer teammates → more RP per win.
Net climbing speed = win rate × games played × RP per game. Stacking boosts the first factor; solo boosts the third. Learn the RP gains and losses and RP modifiers to see the math.
Solo Queue: The Full Picture
Pros: full RP per win, total schedule flexibility, no coordination overhead, forces self-reliance (you improve faster as an individual).
Cons: teammate variance is brutal — throwers, no comms, tilted randoms. Every game is a dice roll on four strangers.
Solo queue works if you’re significantly better than your rank (you carry the variance) or if your schedule is unpredictable.
Duo: The Sweet Spot
One reliable partner eliminates 25% of the variance — no more full-random teams. You keep full RP efficiency (no squad penalty for duos), keep schedule flexibility, and gain a trading partner, a drone buddy, and someone who actually communicates.
For most players, a good duo is the fastest climbing setup. See how matchmaking treats small groups.
Trio and 4-Stack
More coordination, majority control of the lobby — but scheduling gets harder, and you’re increasingly matched against other stacks. Good for serious sessions; overkill for casual climbing.
5-Stack: Maximum Coordination, Maximum Cost
Pros: full comms, practiced executes, zero randoms, the most fun way to play Siege.
Cons: squad RP penalty (less per win), longer queue times, tougher lobbies (matched vs other stacks, smurf risk), rank-gap restrictions limit who you can queue with, and stack dependency — you stop learning to adapt to randoms.
5-stacks are best for pushing at season end or playing with friends, not for pure RP-per-hour efficiency.
When Solo Is Better Than Stacking
1. Your stack is bad — tilted, unserious, or worse than randoms. 2. Schedule mismatch — waiting 40 minutes for the squad to assemble kills your volume. 3. Big skill gaps — carrying much worse friends tanks your win rate. 4. You need individual practice. 5. Your stack only plays tired/late-night sessions.
A bad stack is worse than solo queue. Be honest about which you have.
How to Find Good Teammates
Where: R6 Discord servers, in-game (add good randoms), community LFG channels.
What to look for: communicates, plays their role, doesn’t tilt, similar schedule, similar goals.
Red flags: blames teammates constantly, one-tricks and refuses to flex, only plays tilted late-night sessions, big rank gap.
Squad Roles and Shotcalling Basics
Even a duo benefits from roles: one entry, one support/trade. In bigger squads, designate a shotcaller for executes — not a dictator, just the person who makes the final call so five people don’t freeze. Agree on default setups per site before the match, not during.

Frequently Asked Questions
Is it easier to rank up solo or with a team?
A good duo or trio is fastest for most players. Solo is viable if you’re above your rank’s skill level. 5-stacks are fun but RP-inefficient.
Do you get less RP in a 5-stack?
Yes — 5-stacks face a small squad RP penalty per win, plus tougher matchmaking. The trade-off is higher win probability.
What’s the best stack size for climbing?
Duo or trio for most players: meaningful variance reduction without the 5-stack penalties.
Can you reach Champion solo queue?
Yes, but it’s the hard path — you need a win rate high enough to overcome teammate variance every game.
Why do I lose more with my friends than solo?
Common causes: skill gaps, unserious play, tilt spirals, or playing at bad hours together. A bad stack underperforms solo queue.
How do squad rank restrictions work?
Copper–Emerald: within 3 ranks. Diamond/Champion: within 2 ranks. Too spread = can’t queue ranked together.
The Bottom Line
| Queue size | Best for |
|---|---|
| Solo | Flexible schedules, self-improvement, smurfing your own rank |
| Duo | Fastest climbing for most players |
| Trio | Serious sessions with trusted players |
| 5-stack | Fun with friends, season-end pushes |
Get a good duo. That’s the recommendation for 80% of players. Everything else is situational.
