The minions will be all killed when a Necro changes “Slot Skills Bar” into a none-minion-build. for example u summon Shadow Fiend then u jump into water. The Slot Skills Bar is forced to change and if u have no “Summmon Shadow Fiend”(yes there are 3 m in the skill hint panel) skill the shadow fiend is killed by the god…
This means a mesmer could kill all minions by hit MOA key. While MOAed, the Slot Skill Bar changed and Necro will lose all his/her minions and the skills are on CD again.
Please, just stun the minions while a Necro change his/her slot skill bar under constraint( be transformed , slip into the water)
