7 Hours playtime at Frontline

[TiaHariberux3]

Looking at the Ranks in PvP, there are Players with 160 fights.
1 fight lasts 20 min. That's 3200 min for one Week.
That's about 54 hours for 1 Week and 7 hours per day without Queue time
That's for Frontline. Other contents are lasting 30min. That would be even more playtime.
How is that possible?
In my case i can do 78 fights per week. And i'm playing each day nonstop from 4pm till 2 o'clock in the morning.
Sorry for my bad english.

Depends of which gc you are in I got 130+ in adder chaos dc also most of the 160+ matches are on jp datacentre they have almost insta queues at prime time.
