First of all let's talk about cost. A lvl1 Brewery requires lvl20 Granary, which is a big investment. Basically you can't take advantage of brewery early game. Of course you'll get lvl20 Granary eventually anyway. But just look at cost for lvl10 Brewery: [TABLE='class: wikitable']
[TD='class: wikicell']13465[/TD]
[TD='class: wikicell']8580[/TD]
[TD='class: wikicell']11530[/TD]
[TD='class: wikicell']16050
[/TD]
[/TABLE]
That's pretty big for 1% in my opinion. But wait, let's look at the cost for lvl15 and lvl20:
[TABLE='class: wikitable']
[TD='class: wikicell']46270[/TD]
[TD='class: wikicell']29475[/TD]
[TD='class: wikicell']39615[/TD]
[TD='class: wikicell']55145[/TD]
[/TABLE]
[TABLE='class: wikitable']
[TD='class: wikicell']158980[/TD]
[TD='class: wikicell']101270[/TD]
[TD='class: wikicell']136115[/TD]
[TD='class: wikicell']189470[/TD]
[/TABLE]
All that for 1%? Some might say offense % is rare, but it's not. Siege attack gives you 33% and hero gives you 20%. Now we're looking at 100k+ each res for an additional 1%? No thank you! And did I mention I can't aim my catas? That's a pretty big deal.
And before you say "Just don't get the building then", let me stop you right there. I'm already not getting Brewery. So you can't tell me to not do something I'm already not doing.
