So I would deeply recommend you to do only these tasks:
- Warzone 4 tasks:
- Ordnance (lvl 100)
- Measurements (lvl 100)
- Uncharted territory (marking 3 points: lvl 100; marking 5 points: lvl 200)
- Warzone 5 tasks:
- Home improvement (lvl 130+ luring the lost exiles to the entrance)
- Subterranean life (lvl 130+)
- Warzone 6 tasks:
- Pesticide (lvl 130+ do it on the tasks of the WZ 5)
*Explosive growth is pointless to do in any level in my opinion, if you are not doing it with other players.
To do the WZ in a huge time you don't realy need a super high level, but yes to be carefull, I would say minimum lvl 200-250, but you will be in danger if you don't watch out the dangers:
- Wz 4: The boss is normaly kept northwest of the room, all the team stays in the left part of the room, you need to be carefull about the lava explosions and the summons.
- WZ 5: Normaly all the people suround the boss and the druids mas res every1, so the only thing you have to do here is not to place in front of the boss and to magic wall the volcanos in the north when they are about to explode
- WZ 6: this could be the most dangerous boss, it hits realy hard, so dont stay in front of him never.
