I was gonna do that too, that's how I started with the alt, but frankly it seemed silly to me to rely on troop upgrades alone to raise exp when it is so much faster to do a bunch of low level defences... Different end goals I assume. I want to get my alt built up to where I can make a fast LB push taking advantage of all of the VP hidden between radar 8 and 20. Wasn't the goal at first, I just wanted to see how far you could go these days with the Klattu strategy, but I got impatient.
Wow, awesome VP for the level! Spock, is your radar maxed? My biggest issue is spawn count.
