Machines can, of course, be upgraded, but the chance of them appearing is only 2%, and if you choose machines, it's not for a tent, but for an enchanted ballista.
Firstly, as correctly noted, elves have only a 2% chance of machines appearing. When I start playing, I envision the hero I will have at level 20 and try to choose skills and abilities according to a schedule, but if you are lucky and machines appear, I would recommend that elves take the tent and upgrade the machines to the expert level. And nothing more! In my opinion, it is better to spend 2 levels on other skills than on a ballista.
Secondly, regarding Wingrael! Yes, he is a strong hero!!! +1% is a good bonus, but let's look at what the Mage will have - at levels 20-25, the Mage will have about 20 units of knowledge (including artifacts), which equals +20% Initiative. You will agree that this is approximately the same as Wingrael's level. Another matter, in my opinion, is Ossir; he is the best hero for the Elves, because the main strength of the Elves is archers. Archers WHO IGNORE 75% OF DEFENSE!!! WHAT:eek:??? THE DEVELOPERS were joking))) + let's add the Rangers' ability (sworn enemy) - it will be quite an interesting sight in the final battle!!!:smile19:
p.s.
In general, we can draw conclusions - the Elves are a race more suited for duels than for battles on maps. It left me with strange feelings. I won't say that I liked it, but I have slightly changed my attitude towards it. But still, it doesn't suit my play style, so I leave it to you, dear lovers of rangers:smile26:
