Greatbow balance

That’s open to debate, really, depending what you are balancing your game around. If balancing around game-play, then having weapons types that are effectively moot is not a good thing.

You will not be as good as with 8 dex, yes. But that’s only an issue if you planned to rely on dodging. Which is a strange choice given that simply outrunning things or having good armor is more reliable.

There are 4 or 5 professions that start with night vision bionics. And with “night vision” train you will have ok night vision even with 4 per.

Not true. You can train trapping skill instead.

Namely? I play with this build and I failed to notice that.

The baseline for balancing stuff is a multi-pool character.
