NE vs Orc 1v1

[WES]

k, noted. I'm often 80 food, btw.
I heard, when elf, you should either be 50 or 100, but idk.
Is it wise to stick to this rule, in general?
I have an SC:BW background, so I always have enow production facilities (like, 6 winds or more usually, etc.), many wells, upgrades and expoes. I mean, my macro is OK, but still I often lose to an attack when I'm staying at 50. But then, it may be because of the lack of scouting?

I recently started going for a hundred, like, ASAP and go kill somebody, expanding more in the meantime, instead of hoarding. This way my heroes get better lvls and as for gold, I noticed that when you go 100, you still accumulate some nice amounts of $$, I think this is because your army is so big and mighty, you don't lose units and hence don't have to re-produce them.

I definitely should use scrolls more, though...
