I meant that you can use energy drain to get some MP back. For example when you are dpsing and you have Aetherflow ready and you didn't use the 3 stacks.
You have 1 ability that will always give you back MP, and another one that you can choose to use to have some MP more and also to deal damage.
AST haven't much choices: as AST you only have LA to refresh your MP.
