I'm sure you heard of the new world Azteca that is planned to be released in November. This world consists of Dinosaurs, New Level 88 spells and gear, mounts and a lot of other great things! If you would like to know more about this world go to this link: https://www.wizard101.com/game/community/update-notes/november2012
Now to seeing if the Wizard101 worlds is going too fast, if you don't want to read this you can close out of this post. Here it is.. Ask yourself how fast the worlds were released in 2008, 2009 and 2010. Now ask yourself how fast the worlds are being released now, 2011 and 2012. Here's a list of worlds from 2008- 2010.
2008-2010
These were much easier years to level for me, were they to you? In 2008 they had the main worlds up to Mooshu. They released Dragonspyre in January of 2009. Then Celestia was released in October of 2010. That was a very lengthy amount of time to level your wizards through the world and not go too fast. I loved this time period, that's how I made so many Wizards and enjoyed leveling!
2011-2012
Not my favorite period of worlds being released. They waited over a year to release another world Zafaria , I didn't have any trouble accessing this world, all of my Wizards were at this place and I'm not worried because I'm only planning on leveling a few wizards. I leveled my fire, storm and ice through and then another world was released.. Avalon, in May of 2012, months ago. I only leveled my fire and ice through this world and now Azteca is planned to released in November (next month). Its going way too fast Kingsisle.
Dragonspyre+Celestia= 21 months
Zafaria+Avalon+Azteca= 12 months. Unbelievable.
This is why a few people are having trouble leveling through the game now days, KI if you're reading please go a little bit slower, I love the worlds you're adding it just makes it less enjoyable to level fast and then hear people begging for a new world after a few weeks!
