Which faction do you like the most?

The Academy still evokes slightly more sympathy in me than the Dungeon... just a little, but it's ahead. In general, for something like the Library, you can put up with a lot. I really like using magic. Here, everyone is criticizing the Gremlins, but the resurrection of golems and ballistae is a pretty strong plus for a Tier 1 unit... Plus, I like ranged attacks, and here the Tier 1 units can shoot... it's easier to take mines in the first week than with zombies, don't you agree! We can easily and gently eliminate some peasants and skeletons.
And the Rakshasa? It's... I don't even know what it is, especially if you enhance it with an artifact that increases speed, morale, and initiative! I'm actually afraid of them myself!:D
Of course, the mages are very disappointing with their ability to kill everything. You don't even know where to put them. And you can't protect them either - that's a serious drawback. But you can always aim... and they can take out several squads at once - especially the original squad and its phantom!
Well, as for the Titans... they really have no competitors in the 5th part at Tier 7. And that's a shame... but it gives me another reason to play as the Academy. In general, I have had a reverent attitude towards Titans since the 2nd part: a Tier 7 ranged unit! A dream! A dream for those who like to sit in trenches...:D

Gargoyles are just terrible, they can only be used to counterattack and prevent archers from shooting, and the Djinns are no better - they just die immediately. No mini-artifacts can save them.

Well, they don't save them... It depends on what mini-artifacts! If the artifact is created by a hero of level 20+, then it helps a lot. Put an artifact on the Djinn that increases defense, hit points, and gives magic resistance - and voila, try to bite! After equipping such an artifact, my Djinns bravely went on the attack, and didn't just sit around casting spells... Although, the fact that they are large really hinders them. It's simply impossible to reach them.:(
Oh, how good are the mages and Titans, adorned with artifacts that increase initiative, attack, and luck! It's just awful.:p

And I play the most with the Elves:) I've always liked them:) And they fit my favorite tactic - "keep the enemy at a distance and attack from afar" (it's a simple tactic, I know, it doesn't work well in 5, so sometimes I have to come up with such tactical tricks! oh dear:) )

Yes, it's my favorite tactic... It's called "I feel sorry for the bird," I wouldn't want my units to be hurt...:D The Elven archers in the 5th part are just awful, worse than a nuclear war... The best archers, IMHO.
