Balance changes

Balance changes are changes to a game that aim to adjust different gameplay elements. All types of balance changes shown on Bloons Wiki are marked as Buffs, Nerfs, and Changes. Most games except Bloons TD 6 log specific balance changes in-game, while every balance change for all games except Bloons TD Battles Mobile are shown on Ninja Kiwi's respective social medias. However, some balance changes are omitted and are instead discovered by the community, marked as "[undocumented]" to distinguish them from those expressly marked by NK.

For specific balance changes per game, refer to:
 * Bloons TD Battles Mobile/Balance changes
 * Bloons Adventure Time TD/Balance changes
 * Bloons TD 6/Balance changes
 * Bloons TD Battles 2/Balance changes

Definition
Bloons Wiki defines balance changes in terms of logs. These "logs" are categorized mainly into "Balance changes" and "Bug fixes and general changes". Logs are used to list a series of gameplay changes to a game. The wiki's use of the logs are mainly oriented in the point of view of favorability of community gameplay, with some exceptions if stated explicitly in the log. All entries of a log should be clearly specified, especially if there is any potential ambiguity in factuality.

"Balance change" logs are defined for logging all changes to a certain game entity that have enhanced the usefulness of an entity. Regardless of whether it was written expressly by Ninja Kiwi or not, the community has the final say in defining the "good" in a change of a game entity and its features. However, logs on the wiki are generally based on the philosophy "Does it make it more fun for the player, and also perhaps make it easier to utilize this game entity? Or does it make it annoy the player, and perhaps also making this game entity less useful?". In most cases, the community perception is what decides a certain change a "buff" over a "nerf", or a "change"  if it cannot be feasibly defined as either.

"Bug fix and general changes" logs are defined for all miscellaneous changes of a game entity. Examples of these include minor bug fixes, description changes, and visual changes. Ninja Kiwi may list some of them under "general changes", but again, the wiki community decides whether these changes are game-defining or not.
