Humans got strait buffed with the 17 to main stat.
You keep saying this as though getting 17 in your main stat is the only thing that matters and there's no possible build in which having +1 to all stats could be beneficial. We get it, you like this new system, but your idea of what is and isn't optimized is irrelevant. Some people (quite a few by the looks of it) prefer the old system and would like an option to bring it back.
