I'm quite happy about this as it means on event days (dungeon runs etc) when I get home from work and log in, I won't have to miss out on local leves or battle leves for a new class I'm ranking up due to time restrictions and ultimately missing out on the reset

I'm sure if it becomes exploitable then they will adjust it, like they have the current leve rewards in only getting SP at the end of a completed or handed-in leve.
