Allow Dancers to have the trait: "Auto Regain" and "Auto Regain II". This will give Dancer's 2TP/tick, but to prevent abuse or balance issues, allow it only to activate while engaged with a target AND have enmity on the current target. This will prevent Dancers from engaging a target from afar or with Sneak/Invisible on and accruing TP risk free.
This will aid in generally increasing the amount of TP a DNC has to work with.
While on the topic of Dancer TP, please allow the trait "Conserve TP" to be able to activate on Sambas/Waltzes/Steps.
