I do like the unearthed arcana articles, but I am really irritated about thefact, that new races only have a combined +2 to ability scores instead of +3 like most races of the PHB...
I am also not very enthusiastic about the swashbuckler rogue. The ability to always use sneak attack in melee as well as the panache ability is causing me headaches. A one minute dominate with no means of escape (and nearly no means to resist, if you consider the rogue will have at least a +10 bonus on that check). Being 60 feet away is too much... a normal character can´t close the distance and the rogue can attack and escape 60 ft again.
The ability needs the condition, that if you are attacked by a rogue´s ally, it is automatically broken, and you need at least a chance to escape.
Also the ability is at will... so the rogue can keep it up forever... should I go on?
