Dual spec issues and how to fix them
Dual spec is very handy, and I've already started relying on it for increased flexibility in setting up my 10-man raids. However, as may be expected with a new feature, it is not without its bugs. From extra talent points to missing talent points to things not switching correctly when you swap specs, I've seen a lot of errors pop up over the last few days.
Fortunately, most dual-spec errors can be fixed by one of the following steps:
Reload your UI.
Log out and back in.
Reset your UI entirely (I haven't seen this help anybody with dual spec issues, but the blues are suggesting it, as always).
Of course, if none of this works, a GM can usually set it right. Ancilorn is also suggesting some work-arounds for specific issues, so go check his post in case you're having resistant issues.
