Do you prefer armor or attack?

Skills are, in my opinion, equivalent. We tested: Tazar, level 20, with 10-10-1-1 stats and 1 Archangel, against Kreg with the same parameters, level, and Archangel; they deal the same damage to each other!!! But from the point of view of fighting neutrals, defense will be more reliable. For example, if you give a neutral unit Defense and it runs to our archers... There are many different situations. And D or Space can be very decisive! Especially when you don't kill a unit in one hit and it doesn't kill you!!
