Shear wall reinforcement through the plan and elevation?

I’m working on 14 storey concrete building. I’ve done response spectrum analysis and (because of different walls patterns in each direction) I’ve got in one direction almost half Base shear reaction than in the opposite. How should I reinforce the walls through the plan and elevation?
What is yours common praxis to design (for example shear) such kind of structure. Do you use same shear reinforcement in both directions and consequently over design one direction. Or, you just blindly follow design/Capacity demands for each wall in the plan? What do you do through the elevation?
My philosophy is to choose two or the most four (for each direction two) shear reinforcement arrangement and use them on the whole storey plan. Then I use such arrangement through few storey’s (critical zones) and after them I slightly reduce (in the few storey’s step) the reinforcement arrangement (amount). I’ve also pay attention that the ratio between each reinforcement arrangement is approx. less than 2!

Thank you for all your comment.

There is no reason to detail the lightly loaded walls with the same reinforcement as for the more heavily loaded walls. My practice is to draw elevations of all the shear walls, and show the required reinforcement on each wall. This can also be done by scheduling the reinforcement. You shouldn't "blindly" follow the analysis, but rather make logical decisions about where to change the reinforcement to facilitate constructability.
