Well you can allways just buy/forge/collect gear that supports builds with less dex^^ but im not rly into spending my time and money onto gear i will only wear for about 1 month max.
Also you get more points after lvl 50^^ 5 after 50, 7 after 60, 9 after 70 and so on. So in Late lvl's you can focus more in your "main stat".
