The most difficult alternative

Yes, young man, I don’t play as a Warlock – that combination of skills doesn’t inspire me. First Strike is one of the most useful spells, practically for any monster, but it will be even more useful against Chaos Dragons with their fear ability. Of course, you need to be careful with Chaos Dragons so as not to harm your own units and lose fewer of them. But the army that can withstand 20 Hydras may not be able to withstand 10 Chaos Dragons. However, everyone determines their own priorities in the game and chooses the strategies and tactics that they like best. By the way, I agree with or don’t object to most of your priorities, and I only pointed out the obvious flaws.
