Binary spell calculation #9
Description
Currently, we use a definition for binary spell that may be wrong.
For AQ, we had to flag some spells to be binary, maybe a cleanest solution exists.
Cmangos uses this definition, should we update to it?
Also, if we update the current binary definition to fit cmangos one, I guess we have to take a look in cmangos/issues#1193 , cmangos rewritted their spell system, I know Elysium core got is own spell system, but maybe some points can be forgetted, it's why I think we will need to take a look at some point.
