The Guide of Silkroad
An active guild with an active union of Silkroad that plays a main role in the process of grinding. The active guild added the chance to have an auto share party which no doubt improve the exp get much more than solo grinding. This grants you the chance to level up faster or either farm with a gap. Of course your guild members won't mind if you are farming, because most of them will be, however the reverse case occurs in parties from other guilds. They will only want full farmed players, so they can achieve the maximum damage possible. Not to mention, if you are disconnected, your guild members will wait for you in game, other parties wont. Also the character handling of you and your guild mates plays a major role, for instance if a cleric or a bard gets disconnected, how your party can handle the situation by experience and try to survive also contributes to the leveling process.
If your guild members are always there for you the chances of getting a complete party, or either a perfect grinding is optimized. Also, if one party member loss occurs, a replacement is available from the guild mates as long as they are not AFK. Other sorts of help could either be, they could lend you gold to buy gear, gift you any drops they don't need, stall your cash items once they are AFK, and so on.
