Chang Ws Wei Sheng is a Malaysian professional Dota 2 player who occupies the role of Offliner. His signature heroes are Timbersaw, Marci and Broodmother. In April 2023, the guy reached the 11,000 MMR mark.

Ws started building his cybersports career in Dota in 2021 in the ranks of the Royale 5 team. At first, the team unsuccessfully tried to qualify for the DPC League in Southeast Asia, and then won the League of the Truth Season 2. On September 6, 2021, during an appearance at the QH Sports Dota Series 2 and FDS Esports Invitational Season 2 Royale 5 was disqualified from those tournaments due to account sharing, and its players were banned by tournament operator Oceanic Esports. Following this incident, Chang resigned from the collective.

On September 26, 2021, Ws joined Atlantis, with whom he immediately won the Epulze Monthly Cup: November 2021 - Southeast Asia. In 2022, the team qualified for the DPC SEA 2021/2022 Tour 3: Division II, where they finished the season in 5th place. In addition, the team won the silver medal at Moon Studio August Mood 2022 and placed in the top three at Khaz Modan Cup Season 2, Khaz Modan Cup Season 4 and Asian Battle Arena Season 2. Ws also helped Team Orca win the BTS Pro Series Season 10: Southeast Asia by playing as a stand-in that year, as well as winning the Commonwealth Esports Championships 2022: Open Event with Team Malaysia.

In March 2023, Ws left Atlantis and joined Horizon, where he finished 5th at DPC SEA 2023 Tour 2: Division II. Chang went on to play for Rectify and Gengar for a while. With the latter he reached third place at Mastercup SEA 2023 and then joined BOOM Esports, with whom he played The International 2023: Southeast Asia Qualifiers.

In November 2023, Ws moved to Talon Esports. With his new team, he placed 9th at ESL One: Birmingham 2024 and 1st at RES Regional Series: SEA 1.

In 2024 with Talon, Ws placed at ESL One Birmingham 2024, Elite League 20 24 and RES Regional Series SEA #3, as well as winning RES Regional Series SEA #1 and qualifying for The International 2024. Before TI13, Talon played at the Clavision Snow Ruyi Invitational, where they finished in the top 8. At The International 2024, the team also failed to make a significant impact, finishing only 13-16th, losing to BB Team in the first round of the lower bracket playoffs.

After failing at the biggest tournament of the year, Talon went to BetBoom Dacha Belgrade 2024 and eliminated as one of the first teams to go. At DreamLeague Season 24, the team suffered the same fate: they couldn't even get out of the group stage. In December, Talon Esports became the champion of the MESA Invitational 2024.

The team started 2025 with a 5th place finish at FISSURE PLAYGROUND and a 9th place finish at BLAST SLAM II. In March, the team competed on FISSURE Universe Ep.4, but failed to secure a prize-winning place and in April, the team participated in ESL One Raleigh 2025, but also faced difficulties and failed to advance beyond the group stage, as well as at PGL Wallachia Season 4.

In early June, the team participated in DreamLeague Season 26, finishing in 3rd place. In July 2025, Flipster Talon exited Riyadh Masters 2025, finishing in 10th place and earning $75,000 in prize money.

On October 6, Ws joined Vici Gaming. In October, the team competed at FISSURE PLAYGROUND 2 but failed to advance past the group stage.

On January 8, 2026, he officially became part of Aurora Gaming.

At the first tournament of 2026, FISSURE Universe: Episode 8, Aurora Gaming became champions after defeating Team Spirit in the grand final. At the next tournament, DreamLeague Division 2 Season 3, the team also managed to become champions.

At the following ESL One Birmingham 2026, the team finished in 5th-6th place after reaching the playoffs. Later, at PGL Wallachia Season 8, the roster advanced to the grand final but lost to BetBoom Team and finished in second place.
