The most powerful warrior.

No, killing goblins shouldn't be the main objective. It's right to focus on someone else. But it's better to eliminate them quickly, as they take too long to kill. Regarding the cyclops' ranged attack – it's much better than the current implementation. Okay, you can approach, attack, and cast spells, but it's noticeable how much it weakens them numerically.
Regarding archers – I've said everything and will continue to say that they are the best tier 3 unit.
