+1 Energy Regen bonus - is it temp or not?

[yoyo1]

There is no official answer on that.
it is really confusing, unlike health regen there is a unit for that but the unit has 0 stat

So what is it temp? - than I stop opening crates - why waste my time?
no temp? - I start using gold...

I know that this question was asked in some threads, but was never answered.

It is temporary. A person in our faction found that out first hand

I think this is the first time I've received a +1 Energy Regen bonus, can anybody tell me what it actually does?

[bam bam.]

^^^Gives u 4 energy every min. Well, for a few days, then u go back to 3.
