A class is a style of gameplay which determines the role of a character (defense, offense, or support), type of weapon (Twin swords, lance, axe, greatsword, disc, bow, staff, arcannon, powerfists, scythes, shuriken or scepter), armor (metal, leather or cloth) and skills available for a character of use.
Wetland functions and ecosystem benefits. Wetland functions are defined as the physical, chemical, and biological processes or attributes that are vital to the integrity of the wetland system. Because wetlands are often transition zones (ecotones) between terrestrial and deepwater aquatic systems, many processes have major implications for species. Since wetlands may provide food and habitat for many terrestrial and many aquatic species, wetland biodiversity is often higher than that of adjacent ecosystems.

Often conjuring images of dank, smelly, mosquito-infested wastelands, upon closer look, wetlands are actually biologically diverse and productive ecosystems.
