make them more usefull please.
if u r not a fighter, than weapon focus doesnt mean anything to u. +1 to-hit? pfft
may +3 to hit? or +2 to hit +2 damage? just make it better please

spell focuses a bit usefull, especially for wizards. but for other classes (cleric for example) its so expensive to use a feat for +1 dc (only one scholl)

spell focus should give a dmg bonus to it's scholl
for example evocation focus gives %10 dmg bonus to blade barrier or acid spray

just a idea to make it worth a feat
