i suggest to make that: name based functions that query informations id based.
For example debuff xyz is active or players has skill X or skill Y has cooldown.
This woud be a huge advantage in writing plugins language independend --> plugins only need language support for translated texts and not for functionality --> performance advantage, advantage for turbine cause id based system is easyer to maintain.

BTW: The hole ui shud be language independ: all languages shoud have english command support in extra to the enabled language.
This woud be an advantage for the support, for players and the plugins.
