To answer that question, I'd like to say that the players of this server specialize in a variety of elements, but the most common is Poison, Water, and Shadow. Element juggling is quite confusing for some people, but the majority of armor cards usually fall down into Ghost, Holy, Neutral, and Shadow. To compensate for the lack of elemental armors, people usually carry around Elemental resist potions to adapt to the elemental changes.
Oh and yes, people do ygg a lot since it could be obtained easily. ForsakenRO is a no-holds barred dueling arena of pvp enthusiasts. You are entitled to every option available for you to win, and all you have to do is to trick your opponent out. If you're new, try going to @warp for_fild02 and autoloot yggdrasilberries. Now, there's also the mining quest that allows you to venture into a larger dungeon called the for_dun01, wherein mobs drop yggdrasilberries at a much larger amount.
About the guildmaster of Heartless Inc., that I am not sure but lets not mention any more foreign servers aside from our own ForsakenRO.
Should you have any more concerns, don't hesitate to ask.
