So slow leveling is still really good in the sense that the tower is a complete breeze to go through, but now that PvP has been reworked, there doesn't seem to be an instant advantage to it.
I know there's not a lot of slow levelers left in the community, a lot of people gave up on it when you were unable to retreat from battles in single player, and more people are probably fast leveling after this pvp update. But, nevertheless i would like to hear from the few of you left. Chances are I will never break my slow leveling account, and i'll probably just use another account to get to max level as fast as possible.
For anyone wondering, i'm a level 29 around 300 days in with a few 6 starred heroes (Ponifex and most great summon heroes). Most heroic summon heroes are 4-5 starred.
