After last night's NB I've worked out some mathematics.
Last night's NB ended in 47 minutes. 5 rings were given out to Immo/NM.
They apparently got it in the North-West, and the South East of the map. Now the NW is virtually impossible for us because Immo are camped there and you need a lot of people to lure bosses from all around the map and zhen in a central spot. The SE as we know is camped by NM since the merge.
So what now? The final remaining spot is the north east we were before, except we have to kill 2 bosses - the fire and the ice. The sandbug won't cut it, however, it can be used as bonus pills, if you like.
To put in perspective, what happened in NB was that 600 pills were obtained in 45 minutes. This equates to 13.3333 pills a minute.
So we have 1 min 48 seconds to kill a level 2 boss, or deal 23,148 damage a second continuously for 45 minutes.
This implies we need at least 10 in a room for any hope. This is because we have to lure both bosses and avoid utopia.
It is very hard, without controlling both rooms. That's the state of play at the moment.
