About that modified rogue idea. what if you also got rid of trapfinding and trap sense and evasion and gave him 10+int skill points a level and the ability to use bardic music more than once a day/level.
that or i say just give him 8+int skill points.
Throw in some virtuoso music ability at levels and let him use bardic music 2 times day/level
do either of those sound remotely balanced?
P.S. i may be overpowering them a bit but i have seen some nasty bards and almost all were that nasty because of thier spells
