Favorites, to battle! - 3

Perhaps it would still be worth reflecting some nuances regarding playing on the Warlord Tower (WT) in the rules, at least the main points. Therefore, I ask players who prefer this version of the game to share their thoughts on this, and I will record them in the rules (it will be useful in the future when we refine the rules, and even now so that it doesn't come as a surprise to some).
What we have at the moment in WT:
1) You can take Galthran as a starting hero.
2) Conflux Castle: can you recruit fairies, birds, or psionic creatures, or not?
... any other points?

If nothing is suggested, I will leave it as is.
