Its funny how peoples maths is off and you want to bring up math if you have 15 out of 15 and can use 15 all you can do is switch them around in the bar no varaiation other then when you use the skill. If you have 8 out of 15 you have more variations due to the fact you can only use 8 at a time. I took higher learning math aka statistics if you had any idea of that concept you would understand that some of you don't know the simple foundation of doing math and I hate math. You have way more variety to top if off in this game/time around the prior games had more skills that were not so useful in certain areas some were ok. This game has more strategy in mind with the idea many people wont have the same build as others having a full bar of 15 and that's all there is for skills brings not much to the table meaning everyone would have the same setup then with a 8 variety without being able to use all of them at once. People need to understand the basics before you attempt to justify what you don't like about a game. I am not the greatest with math but sure as hell know the basics. Please before you try and say there is less variety come up with something vaild evidence other then what you think it to be. A perfect example would be dice when it comes to statistics.
Hahahah dude go back to school please, learn about the pascal triangle, combinations etc..
ok, lets not do the whole 15-15 8-15
let's make it shorter
available skills = {a,b,c,d}
Up to 2 skills from 4 available = 11 possibilities
{} {a} {b} {c} {d} {a,b} {a,c} {a,d} {b,c} {b,d} {c,d}
Up to 4 skills from 4 available = 16 possibilities
{} {a} {b} {c} {d} {a,b} {a,c} {a,d} {b,c} {b,d} {c,d} {a,b,c} {a,b,d} {a,c,d} {b,c,d} {a,b,c,d}
same goes for "up to 8 from 15" and "up to 15 from 15"
So yeah, learn to math.
