Haste, confusion, and burning blade is bugged to the point of super overpowered.
Confusion doesn't halved target's atk value, but it decrease it (i don't know the exact formula), and the worst thing is it can be stacked as many as possible depending on casters's mana, which means targets can have 0 atk value, or even worst, negative atk value.
Haste and Burning Blade spells also can be stacked as many as possible depending on casters's mana, and the worst thing is its effect is permanent, meaning that after the combat is over, the buffed target still have the effect of the haste and burning blade untill it dissapear (whether by disbanding it or target die).
This is seriously gamebreaking, as we can make our units that has low atk value (let's say 10 atk) have hundred or maybe even thousand of atk value by stacking Burning Blade as many as possible, or lots of combat speed by stacking Haste, or making our enemy miss all the time by stacking Confusion.
I don't know if those 3 spells are bugged or not. But i hope Dev Team consider making those spells can't be stacked in 1.1, it is ok if it can be stacked 2 times with correct and reasonable duration, but infinite times and infinite durations? It's too overpowered.
And 1.09 changelog said catapults can't be trained as groups anymore, but the fact proved otherwise.
I hope Dev Team adress this problem in 1.1
