No, just bashing wood is not 'constructive' at all.
The problem is twofold;
1. Some players just hate taking keeps. This will not change. People really don't understand how personal preference works it seems. "Just go take a keeps" is probably the dumbest comeback out there. It's like saying to people in a flowershop with only red roses; "just love red roses and buy them". That's not how it works, people who don't want red roses will just think WTF? and leave to find their taste. Trust me, there's plenty of competition for a few hours of playing DAoC.
2. They RvR in their own way, which should be equally valuable to the realm and thus so portrayed in the rewards. It is not. Unfortunately not all playstyles are given equal thought and we are even further away from a system that considers all those playstyles and incentivizes them to mesh together in a way that is functional for realm defense. (You wanna roam and kill inc? Great. Killing inc in the broader area surrounding an ongoing keeptake will also grant you credit for the keep pool for instance.)
I hope we can work towards a system that incorporates all RvR efforts in a similar fashion in the future.
