you can't have all the perks without the required skill level
and without the perks the skill level doesn't do much
so instead of doing a bit of math on a hypothetical situation that would be too silly to actually use in order to prove your point
look at it this way
you reach level 20, you buy a % increase perk
you reach level 40, you get another one
etc.
now by the time you're level 100 you'll have most if not all the perks in a certain skill tree (one you're specializing in, since you apparantly bothered to raise it to 100)
and will have truly mastered this skill
we've already established your example is pretty irrelevant since it would be foolish to actually go about it that way.
so what exactly is your problem with this besides just not liking it for some reason or other?
cuz i think we can argue about this for eternity while it basically comes down to you just not liking perks and would rather be able to just max out a skill and be done with it
or am I missing something here?
If you read the first post I made in the thread you would see the fix I would like (the longer one on page 4 about Mortal Online). I don't honestly see any change coming in Skyrim, that would be unrealistic (aside from mods). I really don't like the perk trees for more reasons than simply not liking them. I think a lot of them are simply unimaginative. Many are too linear. I also find that only a small fraction of the lv 100 perks are worth getting. One handed and two handed perk trees are too similar, and their 100 perk is not very attractive for example. Without even picking a weapon specialization you chew through any enemy fast enough that the paralyze just doesn't draw me in. These are nowhere near all my complaints about perks. People argue that they make people more unique. I find it rare for someone to have a build unique enough to claim this.
