I have a crazy idea, but it might just be crazy enough to work.
What if you got a character maxed out and then your next character was 5% stronger?
First, your character would have to be completely maxed out, I mean all skills 100%. This should literally take about 500 hours.
Second, you then could start a fresh character, but that character could not be made until you finished your first character.
Thirdly, you can only do this process 4 times. So, your best final product (5th character and beyond) would be 20% stronger. (Hero status)
Question: What do I mean about 20% stronger?
Answer: You normally get 10 points to put in your stats when you hit a level. Now you would get 12. That's all.
Now keep in mind, this process should take 1000's of hours. Only the most dedicated players could possibly get this done.
What do you guys think?
