I'm assuming you're trying to be sarcastic like me?

Seriously though, if you add up all the time you're actually on the game, it's really not that much. You get on, make my few hits, then get off and wait to regen. Unless you count the regen time as "playing" as well but I don't. I do other things like watch TV, talk to the old lady, or play other games.
The only thing that really takes time is war and raiding. But of course, raiding is optional and war time only happens once every 3 weeks. Even then most players get on, use their 4 hits then get off to regen.
If you're talking particularly about this event, I made 100 in 5 days. Here's my timings for this event during the tougher last few bosses:
I log in, go to Crossroads or make a trial kill to get boss to show. - Actual play time 1 minute at most.
I take 3 hits on boss and wait 1 minute so I can make 2 more hits. - Actual play time 2 minutes at most.
I then wait to regen waiting about 13 minutes and take 2 more hits. - Actual play time 1 minute at most. Repeat this until dead.
Total actual play time to kill a boss, 4-10 minutes at most.
I wait to regen for about 40-50 minutes and repeat the above to kill another boss. During this time, I may make a few kills for trials and that will take a few minutes, maybe 5 or so before I have to regen my energy.
I guess it may seem like 24/7 since you need to get on every 12-15 minutes but I'm able to multi task easily so I don't feel the regen times are actually play times since I'm always doing other stuff.
