ROSA
RareWho is ROSA
ROSA is a Rare-rarity brawler. This article summarizes their current competitive performance: best map, toughest counters, and weekly win-rate trend, all computed over real top-PRO battles in the last 14 days.
Over a 14-day window, ROSA has appeared in 3,200 battles with a global win rate of 76.7% and a pick rate of 0.5%. That pick rate is the fraction of matches in which some top-PRO player chose ROSA out of all available brawlers, so it works as a thermometer for how meta they are right now.
ROSA sits on the first paid-rarity step of the collection, the Rares. At this tier the Coin cost to bring them to power 11 stays reasonable and the investment in gadgets and star powers pays off quickly, so almost every competitive roster ends up routing through these brawlers as support or as a specific pick for maps where the kit fits better than higher-rarity options.

The best map for ROSA is Singed Earth in Brawl Ball, with a Bayesian-smoothed win rate of 82.0%. That puts them above their class average in this mode, so it's worth picking ROSA when that rotation is live. A strong showing on Singed Earth usually combines favorable geometry (short ranges or cover) and a mode whose objective fits the brawler's kit.
As the second-best option, ROSA also performs well on In the Liminal (Hot Zone) with a 79.8% win rate. The gap from the top map is usually small; choosing one over the other depends more on the enemy team than on the brawler.
On the opposite end, Slam Dunk (Basket Brawl) drops ROSA's win rate to 47.1%. If that rotation comes up in a session, consider another brawler to avoid throwing matches; the gap between best and worst map can be several percentage points.
Counters and matchups
ROSA loses systematically to RICO: across the 287 battles recorded for that matchup, their win rate drops to 81.1%. If you see RICO on the enemy team during draft, consider not picking ROSA or adjusting the game plan to avoid sharing a lane.
In the opposite matchup, ROSA struggles against TARA too: across 19 battles, ROSA's win rate stays low, around 51.0%, indicating that TARA deals heavy damage. These matchups often decide games as soon as the two brawlers share a lane.
Per-brawler matchups are the smallest-sample metric on this page, so read them with the sample-size badge in mind. A bad matchup with 50 battles tells you less than a map with 500.
Star Powers, gadgets and hypercharge
To get the most out of ROSA in the current meta, prioritize upgrades by synergy with their kit, not by gem cost. Star powers, gadgets and hypercharge change tiers depending on the meta, so the upgrade priority is dynamic.
As a general rule, the first profitable upgrade for ROSA is usually the star power with the highest pick rate in PRO tournaments, followed by the gadget that best fits their role (lane, support, or pick). Hypercharge, when it exists, comes last because it costs more Coins and Power Points and only triggers with a full super bar.
Beyond the immediate meta, the upgrade path for ROSA should prioritize what moves the win rate needle the most: power 11 before gears, first star power before second, primary gadget before any hypercharge. Hypercharges cost a lot of coins and power points and only activate with a full super bar, so their real priority drops toward the end of the checklist.
Weekly meta analysis
In the last 7 days, ROSA's global win rate has climbed +1.9 points compared to the previous 7. That climb is published over a 14-day window with a minimum of 3 battles in each half, so it isn't noise: it indicates the meta has moved in ROSA's favor, usually because of map/mode rotations.
The 7-day trend is precomputed every six hours in a small Postgres table and computed with filter source=global. Full technical details live on the methodology page.
Every percentage on the ROSA page comes from sampling top PRO battles with source=global filtering and Bayesian smoothing, recomputed every six hours. If you want to understand why one map performs better than another or how a rotation affects the win rate, the methodology page covers the technical detail step by step.
