IMO fortified towers are pretty good of a choice..
1. Orcs make cata vs towers @ tier 2 rush already anyhow, only making it easier
2. Cata/dryad push for elf vs human fast expo can actually work now easier
3. Destroyers don't own human anymore this badly (maybe too easy for the human to play vs undead now)
But the fast tower rush is insane ye.. they should increase the wood costs for towers by 10, so the human can't make 3 towers in the instant-militiarush
