In your case I'd also just up tenacity as much as possible. Without G12R pieces and 6 dot health primary mods Nest's healthpool does not receive a considerable increase, so at G11 I see no point in working too much on health stats.
On a side note, either try to keep her speed as high as possible while modding for tenacity (260-270+ preferably) or no speed at all. Nest(s) in the middle speed range (220-230) are the easiest to deal with if you ever use her on defense.
