About the no sense things,
1) This is kind of correct but also would give huge advantage to organized groups vs solo players.
2) You dont need to port out to get buffs, just use Sayha etc.
3) Once you reach top floor move down to TOI 13 which is non pvp zone.
About the suggestions:
1) Sure, pvp makes no point really in an event like this other than abusing baium kill.
2) I dont agree, the way it is now you got a sense of urgency to go as fast as you can, if any scrub can reach top floor and have a chance at baium its unfair for top players.
3) This is ok but i dont think it can be implemented properly as a game mechanic by ncsoft.
Also what we do in Giran is we pull baium down to TOI 13 which is non pvp zone and kill it there, this way people wont abuse the PK system to get last hit.
This event is a good event in terms of reward and fun, you can see all the players of the server and also get some expensive einhasads etc.
