I recently started a new game of BGT (my old is on hold until several bugs get fixed in the next patch) and I rolled a genuine 97 for my Elven Assassin (male, NE) giving him the following stats:
STR:18
DEX:19
CON:17
INT:18
WIS:11
CHA:14
Now I usually stop rolling somewhere between 85 and 90 but I got this one after about 5mins and was at first very happy but then disturbed. As I'll be taking this guy through BG1 too and I don't like using the tomes on other characters he'd end up with 19STR and 20DEX and 19INT which is a bit much for my taste (I could dual him to fighter OR mage and be better than the pure class).
So my question is: If I give in to my lower instincts and power him up as much as possible, how should I try to balance this out? By choosing rather embarrassing party members (brave, brave Sir Garrick) or by specializing in odd professions (only non-magical daggers) or is it no problem anyway and I should jut keep him as he is?
