Red Plague

1) Since when has Ravenna's specialization become "useless"?
2) You need to protect all heroes; if you use portals skillfully, there are no problems in protecting anyone (including a city).
3) But what's the point of playing a linear scenario where all the enemies are waiting for you in one pile?
4) Well, it's a story-driven scenario. If you don't like it, you can always play a map generated in the editor.
5) All enemies are easily defeated with 25 heroes; there are no problems. Several people tested the map.
6) According to the author, a Mentor is simply an unfair build, so it is not added on principle.
7) Using portals, you can control the map in every direction. It only takes 1 hero with Logistics (although you can even do without it) to harass the enemy in every possible way. And only one hero needs to run to the shipyard, and then the rest can be "summoned."
8) By the end of the playthrough, my weakest hero was level 20. If there weren't many losses, everything can be overcome.

You were probably tied to a chair and forced to frantically click buttons on the mouse and keyboard. I've never understood such people... If you don't like playing a map, why continue? Are you a masochist?)
