You mad?
Also, to import UnitIndexer, just add this to the globals at the top:
private constant integer ABILITIES_UNIT_INDEXER = 'A!!!'
And then create an ability based on Defend with the id 'A!!!'.
Then change the race to 0 (hold shift and do it)
and change the icon to something null (" ")
Finally, change the name to something fitting.
That's it.
Erase that stupid Lua script
