Tactics for playing as the Sylvan faction.

1. Why did you decide that the Warlock would take Tactics?
2. What are you going to use to counter Chaos magic at such an early stage of the game?
3. How are you going to deal with Stalkers?
4. If the Necropolis suddenly focuses on summoning, how will you deal with Imps?
5. Do you really think that the Stronghold has what it takes to counter an aggressive rush?

My answer:
1. Because the Warlock's main abilities are spellcasting, chaos/summoning, luck, and logistics (quick mind). (in my opinion)
2. To counter Chaos, I will rely on the high initiative of the alliance's main units. If it's a Winged Horror, I can also take Haste. I will split the archers into 2 stacks, and the druids into their own stack if there are any. I will play close-range to minimize the use of area-of-effect spells.
3. Dealing with Stalkers is simple: I'll mark them as sworn enemies and bombard them with arrows. I can even put Eldritch on the arrows. The Hunters will suffer while remaining invisible.
4. If the Warlock goes into Summoning, that's even better. First, the archers will survive longer. Second, Imps are quite mana-intensive, and the Necropolis doesn't have that much mana (enough for 2-4 casts), and it won't be difficult to deal with them. Mines and Crystal Golems look tougher.
5. I think so, I've played and tested it, and they can, but it's quite difficult. Especially if your opponent is playing as Lethos.
