HoneyWoW gets a big update.
New rates: experience x7, green and blue item drops x2, professions x2 and weapon skills x4. Gold, reputation and honor go back to x1, as on retail, so every achievement counts.
Weekends and daily boosts: from Friday to Sunday experience goes up to x10. Each weekday also has its own boost: Monday and Thursday honor x2, Tuesday reputation x2 and Wednesday profession skill-ups x2. Each day starts at 06:00 and is announced in game and on the website.
Cross-faction play: Alliance and Horde can group, chat, trade and share guilds, the auction house and arena teams. Battlegrounds mix both factions too, so queues pop faster.
New features: transmogrification to change how your gear looks, autobalance in dungeons and raids (bosses scale to how many of you there are, bots included), a solo Dungeon Finder, account-wide mounts, guild houses, guilds without signatures and the option to skip the Death Knight starting area.
All the details are on the Information page. See you in Azeroth!
