For new players the FEP system is very complicated and detailed and if somebody really didn't do their research, they could gimp their character. For example I have only really eaten fish, and my intelligence has therefore shot up very high, whilst all my other attributes are really low. This now makes it quite difficult for me to get my other attributes up, as the FEP needed for a level is based on your highest attribute. The only thing that stopped me and made me aware of the situation was an experienced friend giving me advice..
I propose that the game mechanics would be better if the FEP needed to advance, e.g. agility, is based on agility only, not the highest attribute.
Whether you have 100000000 STR or 10 STR, the increase from 10 to 11 agility, for example, should always be the same.
