The last few days have been a good opportunity to test whether this balance is working. It is way off in my opinion.
Over 5 days from a standing start, people who focussed on building defensively lost big to people who focussed on bomb building on our server. After 5 days, a raiding clan had enough bombs to blow through the 6 T3 doors that protected my inner base and destroy pretty much everything in the base. Not only that, they were able to wipe out two other bases much larger than mine on the same night. This raises two problems for me.
As it currently stands, T3 is not worth the time and effort. T3 doors in particular are pathetically weak. Yes, there are tricks to layer them, but not within 5 days from starting a new character. The same goes for defensive thralls. Hour for hour, the bomb builders are way ahead.
Secondly, what is the thinking behind T3 building pieces being so weak that raiders can go through 3 large bases in a couple of hours. Seriously, where is the reward for people who like to build and where is the challenge for the raiders?
As it currently stands, the game massively favours offence. Raiding should be more of a challenge and building should be more meaningful.
This problem is acute on the new map as it is much smaller and offers far fewer places to regroup undetected after a big loss.
