If you can't get more than 900 point within the first 20 seconds of the event, then you are not prepared.
By not prepared, I mean either
1. Didn't complete far enough in main quest line to open up hidden public quests.
Or
2. Didn't complete at least 5~6 of the public quests before the start of event - could be gearing issue or lack of mount or something else.
If you still not sure about what you didn't do or did wrong, you should try contact the first place of the event (top 3 names are announced) and ask him/her about how to get points quickly.
On a side note, event in this zone isn't for players who just make a character and exp orb/daily level to 67 (minimum level to pick up public quests). Player actually have to complete quest line start from Thunderhoof to SJF, NJF...etc, which involve 7(?) zones of questing. If the player didn't done those, don't even bother with events because you almost never gonna reach top 3.
I personal think the new event is way better than anything we have before - reward/cost is almost same as the gce mento farming runs and didn't turn into a welfare line like the dalanis ones.
