>>3444450>rarer swords I got like Ichigo and Mikazuki
1. You get to experience the dopamine hit of smithing them again by accident
2. They're really not rare when you're trying for event swords, in fact they're a plague
Weigh up the pros and cons for yourself. The game is incredibly free to play, regular event maps change in and out if you get tired of the main maps, obvious achievements, dailies and progression at the start of the game, but everything is samey hands off gameplay and casual grinding. If you have nothing else to do or play then starting anew and messing around a bit isn't bad.
