I just don't understand what (in my opinion) can be downloaded and used for both offense and defense with healers, instead of just sitting in a passive defense, watching how the opponent develops their strategy... Simply summoning against a (smart) Dwarf is just a stupid thing to do. The fact that they won't reposition on the map, given that they have everything, and there are many opportunities to annoy them in the style of Exocet... or with Rings of Exile, which are in large quantities on the map... it's obvious that a passive defense will never bring victory; you always need to combine attack and defense styles, depending on the landscape, the enemy's tactics, and so on. Why just adapt to a specific skill? Moreover, if we know that the opponent didn't go for Chaos, then Erls will completely destroy them because of Chains and Berserkers.
And regarding speed and acceleration, I completely agree.
