Ive been reading this for a while.... and im thoroughly convinced you are arguing for the sake of arguing.
Yes, changing the meta will change your builds. Trickle down effect. This is going to happen no matter what happens in the game.
I myself am very anti-meta. I like to use obscure weapons and generic mod combos and play at very high level content. Like enemy levels with 4 digits.
But heres the truth, and the concept you seem to be ignoring. Just because YOU use limited builds does not change the overwhelming build potential vs majority content.
Warframe in general has an enormous problem with power creep. As you've stated, your limited builds are already enough to deal with majority star map content. Then, adding just a couple more mods as drasiel has shown, and all of a sudden we're roflstomping through everything. The builds dont even have to be meta. You can do non-meta builds and still delete everything.
What Drasiel has clearly outlined here, is that status is merely one aspect of the larger picture of the damage system, and the issues that exist within it. Whether you partake in it or not is irrelevant.
