Well its not really limited... what does makes this question treu limited is the use of the 4 slots.....
Why do i say this..... because you can remove the used skill to try another and there for you can find the 4 best skills.....
Its a game in a game: mastermind with the 4 color code....
If you use the 4 best skills you don't need a fifth one....
So why using 5 skills if you have the 4 best skills already .... it makes the fifth useless....
And serious end game players like me.... 3 is enough
and a ironman would need 2 only if your a treu master of this game.... and if you want to be the matrix of the game you would play it without the 4 skills slots whaha...... proof me your the matrix..... bitches..... :lol:
