Strategy and Tactics

Hello! I've been familiar with the fifth installment of the Heroes series for a while, but I only recently started playing it with genuine interest. I'm the kind of person who, when I get into something, I like to understand it thoroughly, so I decided to write here to get advice from more experienced players.

Here's the problem: when playing on "Veteran" difficulty as the Tower faction against bots, after about a month in the game, an opponent shows up and completely crushes me.

I would like players to share their daily tactics and strategies. I've read a lot online, and almost everywhere it says that the Tower faction is scary because of its push and rush tactics, and that the game needs to be finished within a month. I'm interested in any specific scheme for how these events unfold.

Thank you in advance.
