Do automatic hit abilities kill minions?

[Rel]

If it won't make a different the vast majority of the time, is it worth the additional record keeping required to track temp hit points for a swarm of minions?

(I ask from a devil's advocate point of view. I've been considering giving all minions temp hp equal to their level, although I'm not sure if that's actually wise.)

My opinion is that this is not an onerous quantity of information to track. If the minions get 5 TempHPs then I know that each minion has 6 HP. 6HP is the only number that I have to remember. If a minion gets hit by an effect that does less than this then I have another number to keep track of but that won't happen very often so the workload isn't heavy.
