Zorg Empire

I have enough resources to build a deathstar. I am wondering if I should build it or build a fleet of battleships, battlecruisers, and destroyers. I have a few questions too. Could, say 50 destroyers take out a deathstar? Also, how long would it take for a deathstar to go from 1:1:1 to 1:2:1?

I only use RIPs for fleet-saving purposes (The uber-slow speed makes fleet-saving SOOOO much easier).

RIPs, from my experiences, suck. Horribly.
