"World of Warcraft: Legion" is anticipated to be the expansion that Blizzard needs to rekindle its fans' flagging interest in the game.

Based on the latest "World of Warcraft: Legion" reveal trailer, Blizzard seems to be pulling out all the stops to ensure that old and new players will get their hands on the latest incarnation of the popular online multiplayer game, Neoseeker reported.

Class identity will be making a return; Illidan will be back to tell everybody how unprepared they are for the battles ahead; Night Elf lore will be featured; and the Burning Legion will be making a re-appearance.

If Blizzard manages to pull all of these off, the company may be able to breathe new life into its franchise game which has seen its subscriber base significantly dwindle over the years.

The game developer's calculated build-up leading to the release of "World of Warcraft: Legion" seems to indicate that it has already learned from the mistakes it made in the development of the "Warlords of Draenor."

However, the big reveal that has created a major buzz especially among long-time players is the removal of multistrike from the game.

This is considered a crucial development in "World of Warcraft: Legion," as the elimination of the secondary attribute would result to major class overhauls that would affect Blood Death Knights, Subtlety Rogues, Holy Priests, Survival Hunters, and Elemental Shamans.

Moreover, a lot of specs will be getting a make-over wherein long-time players will have to relearn everything about their main when they get the game's pre-patch.

In an earlier interview with GameReactor, "World of Warcraft: Legion" lead game developer Tom Chilton said that the game has been in development for over three years now, a testament to effort exerted by Blizzard to guarantee the game's commercial success .

"We go through multiple expansions at a time and there was a point in which we were trying to decide the order of which should come first, Warlords of Draenor versus Legion ," Chilton said. "And we had decided that the right thing story wise was for Warlords to come first and lead into Legion.

"So we have known what we are going to do on core level since two and half three years ago or so now. It was around 2012 we were talking about that," he added.

Although no release date has been set "World of Warcraft: Legion," the game is expected to be a hit among fans who have long been waiting for the game to make a strong comeback.
