I agree with that.
In Arathi Basin for example there is an honorable defender buff, which is I think a very good idea vastly underutilised.
A big part of the problem in my opinion is players who obsess over the damage meters, but put that damage into irrelevant kills.
Doing damage relevant to the outcome would be most likely when it is is proximity to an objective, be that a flag carrier or a stationary capture point etc.
