That base hurts my eyes as a builder. *cries*
I HAVE done the attack grangar thing before (because for some n00bish reason, I kept thinking I was a dretch... roflmao. I was going "WTF? Why isn't he getting hit by me touching him?" till he lasered me to death =( )
I don't think deconning the Reactor is a bad thing since many Human bases are simply crap (or very, very difficult to defend well) but I think I just learned something new about the OM. I'll have to think on that one more.
About Arachnid2 and building in that U-shaped tunnel. Check out the thread on good base designs (the sticky) we had a discussion about the base there, and agreed that while it's snipable (as aalmost ll bases are when aliens reach S3 anyway) it IS tight enough that a tyrant is going to either haev to kill himself to cause serious damage, or he's going to have to keep retreating often. And hopefully get cockblocked
Edit: I noticed Norfenstien talking about it

WTG my master.

Nux: *dies laughing* oh man... that's hilarious.
My pet peeve?
As a builder, watching n00b builders think "oh cool these guns can kill the aliens!" and set about building them far away from the base.
Repeat after me: TURRETS ARE THERE TO DISCOURAGE ATTACKS NOT KILL ALIENS.
I (actually, the sad thing... the whole team) fell for the "WTF ARE YOUDOING WHY DID YOU DECON THE REACTOR?" trick before.... that was mean. =(
Non-pushing humans at stage 2 and 3. I mean, I play humans the most. CMON DUDES GO OUT THERE GODDAMNIT!
