Spells which do not trigger the gcd.

[Sam DeathWalker]

A lot of macros here voilate the simple rule that you cannot have two spells in a macro which trigger the global cooldown.

Here is a list for prot pal that do not tirgger the global cooldown, sadly there is no way to get this information except to look up each spell on wowhead, unless someone knows how to data mine the spells data file.

If someone wants to do the spells for other classes Ill provide a table with the spells listed like below, but without the gcd timing. Also this is just for prot with the spicific talents I selected.
