Regeneration In Process
I never heard the "at" variant until I saw your usage of it; is it the Russian convention?
Technically, it is, but as said there are also English sources that use it (though maybe it just seemed so to me; still, you do get some results if you google for "battle at", so that partially proves my point).
Yeah, I mean if I was going to criticism das's english (from a position of weakness myself), I'd go for the overuse of "either"
And also the semicolons. I generally (another word I use way too often) tend to overcomplicate sentances, both in Russian and in English.
But this isn't exactly on-topic, is it?
