But as i understood it, the change in regards to AW's, they still give us an advantage, just not as much as before ?
Every AW level according to MinMax's calculator adds 1 unit per squad to the fight, per round. I can't see how that is more than an AW gives us
And there's only 2 AW's we have that give us nothing, which is Thrones and Blooming Traders Guilds, everything else gives us something that adds to our ability to produce more of something or gives strength to troops or gives free troops, or more goods + boost to both troops and goods production.
I do not know where you get that number from. That is not at all how the formula works. Tourney costs depends mainly on 3 factors (tech, AW, expansion), it is simply not possible to say how much 1 AW level adds to costs without knowing the other 2 factors, which are a) different for every town and b) change all the time (unless you stop progress and never place anymore expansions).
Just as an example (completely arbitrary numbers!):
Town 1: 500 techs and 100 expansions: 1 AW level adds 50.000 to costs
Town 2: 50 techs and 10 expansions: 1 AW level adds 500 to costs
There are many other numbers involved (like constant factors). So this is not exactly how it works, but it explains the point very easily I hope.
And that is only the starting SS. (which means your very first fight in the first province). So yes you can build as many AWs as you like if you never inted to do more than 1 single fight every tourney.
The real costs come much farther into the tourney, when playing higher provinces. Costs grow exponentially as you progress through the tourney. Depending on your other base factors (expansion+techs) and the tourney province you are in, the 1 troop cost in province one can easily be thousands of troops in every single encounter in higher provinces.
There are very few AWs that can produce that amount of bonus, the question for most AWs is therefore NOT IF, but WHEN each of those AWs becomes a burden more than a bonus.
Very few AWs (the direct military ones) have the possibility to overcome that problem, by changing the difficulty of the fight (rather than changing its costs). Which means there are less than 10 AWs that can more or less be guaranteed to be beneficial. All the other AWs are definitely causing more cost than benefit if you play tourneys high enough.
