Tanks are fucking crazy with mass chain, im not sure if its even a good idea to keep it on a pvp server. To be honest Secret of Empire was the last classic, similar to how interlude is considered by many to be the last lineage. Changes are too drastic without really enhancing gameplay or improving on old systems which is what classic was about. The direction they took was what many players wanted to avoid. At least from a chapter system or however you want to visualize it. C1 to interlude, kamael to goddess, goddess to ertheia, ertheia+. Just like early classic to 7s, secret of empire, then kamael+essence.
