Wars versus farming for resources and NTGs are two very different aspects of the game.
We can definitely do with more defense in world wars, but, a boost to offense wouldn't be too bad for farming for resourcing, and when there's a need to 5 star bases to gain NTGs.
Farming for resources and NTGs shoudn't normally require tactics and troop cards. That would be the ideal state.
I believe not many would have a problem with the introduction of more defensive buildings that can be placed only on to war bases, but not on to town bases. I would believe most people are favoring a buff to offense to counteract some of the recent buffs to defense which are applicable to both wars as well as town bases.
In summary, wars where one can attack with troop cards, tactics, mercenaries are one aspect of the game. Continued beefing up of defense to this aspect of the game might not be a bad idea.
The other equally important aspect is the farming, and that's probably where some beefing up of offense is about time.
Cheers and happy gaming!
