Now for the real 'holy **** this is bad' revelation. Those charts, values, etc, are all the actual XP curve. That is before adjusting for learning curve.
Ready for how bad it really is?
This is the xp as a percentage of 275 for the best case scenario where you put 7 points into your attribute and 5 focuses on a skill. So now look at where you are on a skill and realize just how far you've gone towards reaching 275.
Yeah, those guys who are like "I reached 150 in a reasonable time frame" well you gained 5% of the necessary xp to reach 275. "Oh Im at 200, Im getting close now"... nope, you're only 13% of the way to 275. "Im at 250, I MUST BE CLOSE TO 275 NOW!" wrong again! You're only 33% of the way to 275.
"Oh damn, Im at 263, only 12 more skills to go and Im at 275" ... hate to break it to you, you're only halfway to 275.
"274! One more skill level and I can reach 275!" Can I remind you that you're only 90% of the way there? That you still have a full 1/10 to go?
