Why does that make the debate pointless?
A system developing you into an OP character is flawed, however, it is up to the developers to balance things. Now you could argue the new system is balanced (I personally disagree) due to the way enemies scale and assuming you are playing on survival. However, and maybe this was just me, but towards the end of FO3 and NV I still had problems with Deathclaws sneaking up on me, they where still an enemy to be feared. This is simply not the case in FO4, now I just unload a shotguns contents into their faces and they never do damage my way. In other words I think the previous system resulted in a less OP character (still OP).
A debate like this caught by Bethesda may result in a marriage taking the best of both worlds.
Just imagine a FO5 with a ranked skill system (like FO4) where each skill is situational (like SOME of NV/3 Perks), your stats are defined entirely by SPECIAL which you can only raise every five or so levels, and there is no scaling enemies, rather a system in place where a level 50 character can still be taken down by mole rats if careless (because the skills would be situational, and therefore not plain boring buffs to take everything out). It'd be great if it also had a handful of Traits return but with more considerable flaws associated with them, and possibly perk-sets dedicated to each trait.
That to me is a mix of two systems married perfectly, with some advances in areas I personally think Bethesda should be moving towards. Ofcourse that is my opinion, I am sure some people out there would hate it.
