I was afraid you did. How that makes your comparisson betwen a gun with 999 dmg and modding the level reqs for skills to allow for a more flexible playstyle any more logical is far above the current alcohol level in my blood.
You only get ONE skillpoint per level. If you put all these in lets say rifles, you are not more overpowered than you were in Fallout 3, if you had put all points in the gun skill for 4 levels. Battles might become more easy, but the rest harder. In theFO 3 example, you could not have improved sneak, repair and lockpick- thus going into battle outgunned , with less ammo and earlier detected, thus negating your gun skill advantage mostly. The same happens in FO 4. You high rifle skill is not really that much impressive, if your rifle is an unmodded peashooter and you lack everything you may find in higher than basic locked chests/safes etc. In some situations, your skill choices might make things more easy, in others, not so much. Its a fair trade off, and completely up to your decision. However, if you still think that this is comparable with a 1k damage gun, de facto a tgm command, then i will end it here. Please send me a postcard from whatever parallel universe you are living in...
