Depends ^^ yesterday i met someone saying "i hope you need less than 20 minutes per run".
Some prople finds this fast, others are more exigent. My opinion, by example, is that a 10 min run is fast (i need 16-17 min to solo, so i'm a slowpoke
). To others, you're not fast enough with 7 min. ACV is pretty much walking; bosses could die faster than HKT ones, so you need a good running speed first of all. This makes the time.
