The goal of TTW is replicate FO3, but with FNV's upgrades. This add-on, in my opinion, does a pretty good job of doing that. I am kicking around the idea of merging this plug-in into TTW directly and letting a mod boost their power for people who feel it is necessary.
Before the shit storm hits: I agree that Super Mutants are SUPPOSED to be tough, I agree that the current Super Mutants, without this plugin, are about where they should be.
BUT!
As I said above, TTW is here to replicate the feel of FO3 NOT for us to make changes based on how we feel it SHOULD have been done. The only time TTW makes changes is when we feel that the FO3 developers would have done something similar, had they had the resources from FNV readily available to them.
