It is unfair to users that do not buy silk or buy in game gold from illegal gold companies. Silkroad Online Is supposed to be a free to play game, but by making 12D-13D alchemy impossible without either buying silk or in game gold this makes Silkroad Online a pay to play game. Not everyone can afford to spend hundreds of dollars a month on a game that is supposed to be free to play.
The alchemy rates after the last alchemy rate increase event are worse than they were before the increase event, before event +3 on an item was fairly easy to get, +5 was attainable as well, after event +3 is attainable and +5 takes almost 3 times the elixirs to attain. Before event you never failed +1 now failing +1 happens 4-5 times in a row.
