Post-match analysis.

I agree with loi; you need to send one scout. If the blocks are fighting without extra lizards, it's better to use Vipers (scouting will be, on average, 1.5 times faster than with other castles). In my noob opinion, if you build a Viper Lair in the first two days (which requires 15 wood and 3.5k gold), and you don't have enough wood or gold the next day, you might end up with no buildings at all. :smile34:
P.S. And I've also noticed recently that 3 stacks of units from the Swamp appear much more often when the second level is built from the start. Has anyone else noticed a connection? :confused:
