What is the point of the large scale leves?

[Arkenne]

Lazy or not single leves would net u much more in a shorter time.

Normal ones net you much more proportional exp, but the amount of exp per minute is much greater on the temple leves.
If you do 3 temple leves within 10 mins its like you did 15 normal leves in that time frame. And seriusly, they dont take that much longer to complete from the normal ones (most only have double the stuff). So temple leves definitely wins on the time department. (unless you are leve starved and are considering the allowance time reset?)
