Super strength: interacting with the environment, i.e, being able to "lift" heavy objects for different effects (throwing, freeing victims, hitting baddies with heavy objects, etc.). Also, comics, movies, and TV heroes constantly cause collateral damage, and those with any greater than normal strength are always lifting/moving heavy objects for various reasons, busting through doors, even walls. Is it possible to build that mechanic into the CoH game somehow?
Furthermore, the old trailers of the live game often depicted heavy objects being lifted and thrown. Perhaps this mechanic was planned all along.
