Tactics for Fortress against Tower on an XL map.

The game will be good and interesting if, for example, while playing as Crag Hack, you learn and master the tactics and earth magic to an expert level... As everyone knows, mages are excellent ranged combatants, and their magic is powerful, so it's best to engage them in close combat... Much depends on whether you attack the opponent first, as you can immediately use tactics to send all your units forward, and if you attack first, your thunderbird will go first (of course, depending on which race you are playing and whether the opponent has a speed advantage due to artifacts)... Then it will roughly look like this: you apply slow and immediately send all your units forward to eliminate the enemy!!! Direct all your attacks towards the titans and naga, and, of course, position yourself so that you inflict damage on these units while preventing the archers from shooting... Then the Fortress won't stand a chance!
If you play like this against the AI, I think you'll easily win! Against a human player, I think you should act the same way...
