World of Warcraft has grown so large and ambitious that patches can focus on individual meta-games without even touching the main title. The next patch, for example, will focus entirely on the Pet Battles system, working to reduce randomness in matches.

A post on the Blizzard blog states that the 5.3 update will add a "Hit Chance" for all abilities, giving you more information on how likely you are to strike a target. It will increase or decrease based on abilities as well. In addition, the update will remove the default 5% dodge chance and reduced the higher-level dodge change from 5% per level to 2% per level. All of this is meant to let you more reliably fight higher-level monsters, though Blizzard notes that it also made some slight tweaks to abilities that were left with a 100% hit chance after the other adjustments were made.

"In a turn-based game, randomness can be a lot of fun if handled correctly," the blog states. "Without a little randomness, the outcome of a match could be predicted to a high degree of certainty before the first swing, and that's no fun. Randomness often works best when it is opt-in, often in exchange for greater attack power, longer duration, etc. In fact, many higher-damage battle pet abilities already had a reduced chance to hit, which will now be visible."

The blog also notes that it left the base 5% critical strike chance in place, at least for now. The blog has a full list of attacks that will have their damage increased and accuracy decreased.
