It's really that ridiculous progression. I did not play more than 6 hours each day. You get a max amount of 16 quests in the event zone. Those quests are all fullfillable in short time, killing 5-15-40 is made in good population in 30 minutes. When you just have 1-2-3 buffs with each +25% pvp you get alone from killing lot pvp and the rewards are much higher. For an experienced player it is possible to raise low level chars in one event-week a few levels.
