from some korean webtoon i read about mmorpg, it seems they have a different set skill for normal gaming (aka farming) and PvP. skill that can be used in PvP cant be used in normal mode and vice versa. a different webtoon also mentioned the equipment used is also different. so it is possible one good at PvP wont be good at the other setting.
idk whether this is true for real life mmorpg in korea at least. but honestly this setting feel redundant. what do you mean they have to farm, enhance, and burn money for two different sets of equipment?? and they also have to build and learn to use two type of different skill sets for one character??
it is so different from mmorpg i usually found in japanese fiction. they usually have special area where PvP can be initiated but i havent seen one mention the different skill set or armor. they just use their normal skill set as it. it more cost and time effective.
