Each rank tier has its own approach to banning heroes, and similarly, each server—be it Thai, Taiwanese, or Vietnamese—has distinct preferences for banning certain Arena of Valor champions. Some heroes are banned for their strategic impact, like TeeMee, while others, such as Alice or Elsu, may be banned simply out of dislike.
So, how does hero banning compare across different servers? Which heroes are the most-banned on the Thai, Taiwanese, and Vietnamese servers? Let’s dive in with GameBomTan24H’s detailed analysis below.

Dolia
Dolia’s disruptive capabilities—multi-target healing, crowd control, consistent poke, and especially the unique ability to amplify teammates’ skills—make her a top-five ban pick on the Thai server. Unsurprisingly, Dolia is also a recommended ban in several rank tiers on the Vietnamese server.

However, her ban rate in Vietnam isn’t as high as in Thailand, likely because Vietnamese players often favor individual playstyle over meta-focused picks. Dolia, for her part, relies heavily on teamwork. Without a cohesive team synergy (for instance, pairing her with heroes like Erin, Capheny, or Tel’Annas), her effectiveness is limited compared to more buff-centric team compositions featuring Hayate, Stuart, and similar champions.
Flo
Flo’s frequent bans on the Thai server are no surprise; she’s an all-around powerhouse capable of handling various matchups, boasting both resilience and damage output, plus crowd control. In the hands of skilled players, she can easily hold her own in two-on-one scenarios.

In contrast, Flo is rarely banned in Vietnamese ranks. This is not due to a lack of skilled Flo players but rather a preference among Vietnamese players for highly mobile duelists like Yena, Ryoma, and Murad. However, if you’re considering a slower-paced hero for solo lane or jungle, banning Flo might be wise—especially if the enemy team has a “Flo main” that could make the game significantly harder.
Grakk
Grakk is a highly notorious pick, known for game-altering hooks and pulls. While his early-game impact can be inconsistent, a single game-changing hook in the late game can secure victory. It’s understandable that he ranks among the top-five banned heroes across all three servers.

In Vietnam, Grakk is also one of the most frequently banned heroes in Arena of Valor, regardless of rank tier. His disruptive potential makes him a natural ban choice. Moreover, some players ban Grakk to avoid the risk of having him on their own team—when his hooks miss, or worse, when he pulls in an enemy to wreak havoc on his own team, things can quickly turn south.
Murad
Murad is a unique case on the Thai server, standing out compared to the Taiwanese and Vietnamese ranks, where he’s one of the most frequently banned heroes. GameBomTan24H notes two main reasons for this: first, banning him eliminates a threat to Flo, and second, when given a favorable matchup, Murad can play freely and dominate from start to finish.

Those who follow tournaments closely will know the havoc Murad can unleash if left unchecked without counters. Hence, Murad’s high ban rate on the meta-conscious Thai server makes perfect sense.
Aya
Aya may not be as highly prioritized in Vietnamese tournaments as before, but she’s a hot pick in ranked games, particularly on the Thai server, where she tops the list of most-banned heroes. Her ban rate is equally high on both Thai and Vietnamese servers.

Many players are familiar with Aya’s annoying capabilities, especially during the mid-to-late game. This feisty squirrel may be small, but she packs a punch—boasting crowd control, substantial magic damage, map vision, and shield buffs. For this reason, Aya is not only heavily banned on the Thai server but also ranks high on the ban list in Vietnam and Taiwan. GameBomTan24H suspects that many Vietnamese players ban Aya simply because they find her irritating. Are you one of them?
