Developers at least in distant plans are going to do something about this, something to do? In 99% of cases, you can not do anything to a player that outperforms you by attributes, 30% might, speed, stamina - I think that's too much.
Virtually no tactics and strategies will not help. Attributes are also very difficult to get in the amount to surpass the opponent, it's good that they are limited. However, it all boils down to spamming the heroes, in pursuit of attributes.
In the end, the game is called Art of Conquest, a game where you need to think through strategies and think.
Now it is more like Art of Spam heroes. Players getting the 40th level leave the game precisely because they can not compete with such people in PvP. Today I saw in PvP one person:
1. Leader - almost 1500 (30% at.speed)
2. Stamina - almost 1000 (30% hp)
3. Might - about 950 (30% might)
This is an incredible booster for the army. Complete lack of balance.
