Off to a good combat focused start.... you'll miss out on some quest options here and there without a more rounded build, and traps might catch you off guard now and than, but you'll have enough hp to deal with it. Esp, if you invest in Body Development.
Combat orientated builds do well end game. They have to fight but hey, that's what they do best.
The builds that struggle the most in end game are builds that are neither balanced enough to get the good quest options, nor lop sided enough to be beasts in combat. Think just missing trait checks. But even those builds can beat the game without too much issue.
