Druid charm spells
 

Does Allure of the Wild (lvl 44) have a greater chance of not breaking vs Beguile Animals (lvl 34), or is it just a matter of the former being able to charm animals up to a higher level and for a longer period of time?

No difference in charm duration, just maximum level. Allure of the Wild is a disgrace to all druids with the horrible cast/recast time. You can still charm solo to 52 with beguile, and then switch to the properly designed Call of Karana.

Awesome, exactly what I was wondering. Thanks!
