stonehenhe was nerfed at first and buffed afterwards to the previous state after feedback
May tree is better building then stonehenge, just because stonehenge got few extra useless pop/cul it doesnt make it a stronger building
Stonehenge is best production-based evolution building in the game... It has highest production, pop and cult of all evolution buildings.
Highest mana production of all evo
Highest seeds production of all evo
Highest population of all evo (tied with blue phoenix)
Highest culture of all evo buildings, not tied with any other building.
4 KP, most of all evo buildings available.
May tree has:
Weakest pop/cult of all evo buildings compared to it's size (tied with Coldfire) they are all 2x lower than "base" buildings (sirens/gingerbread/platform/golden phoenix which are all the same pop/cult)
Most useless productions (gold and hammers, not needed in high chapters, should be replaced with mana/seeds)
3 KP which is the only good production, but once again - we have enough of KP producing buildings
6k T1 sentient good in chapter 16, which is less than base production of marble manufactory in chapter 15 with low level wonders from chapters 14 and 15 for sentient goods bonus.
I don't know from where you took that the may tree is better than Stonehenge, when Stonehenge is literally the best production-based evo building and May tree is literally 2nd worst only before coldfire phoenix which is the biggest loser.
That's why i'm shocked there no changes to the event at all.
They even ignored people complaining that they got x2 then reveal two and then under last flower is "reset" - which is 20 currency lost on X2 and "reveal two" and nothing gained as reward.
