I think, of course, maxing out melee will be definitely a positive and definitely soemthing you will do easily, just requiring time. For your skill set, like 'Kadaj said, require skills about 50 or + on some occassions. And yea, i understand where your coming from with all your skill sets for 50+ and i suck for not having every skill 50+ yet, but yea, i can understand your reasons, but when the time comes, it's absolutely necessary for you to train those certain skills above 50. I think 60 would be more acceptable because only the real intense quests require 60+ (ex. WGS). so yea, at 50, i think you will be forced to raise it regardless of what is occuring now.
Good luck tho, I support you
