About Warhammer 40Kv3...
Most of you probably already played a few times with the new set of rules.
Since I've got a space marine army, I only know about them.
The defensive capabilities are more balanced now,
since terminators must throw 2+ on 1D6 instead of 3+ on 2D6.
The point is that with this new rule you'll more dependent of other troops,
instead of using them as cannon fodder and then finishing the job with terminators.
