The rogue is still OP on his own because of certain skill (some of them I mentioned in an earlier post page 1) but I think most things that make him OP are bugs or unintended behaviours.
Now I usually have no problem saying you can just ignore certain exploits that are specific.
In the case of the Rogue, you can't just Ignore and entire specialization line, it need to be looked at, whether this is the skills of the scoundrel or the synergy with other skill, there are some combinations that are too obvious and too strong.
