This WeakAura shows a warning when an enemy in Arena/Battlegrounds uses major offensives and most defensives.
Please suggest missing spells in the comments so they can be added and the WeakAura updated.
Note: One shot potential offensives such as Combustion, The Hunt, Divine Toll etc have added red font to emphasize.
If you find spells that you want to add yourself manually, please check the Group Description section of the Information tab on any of the WeakAuras included in the import.
