Avoid Rabble Rousing + Vampirism
Vampirism sets your health regeneration to 0 and prevents you from being healed by allies, which directly conflicts with Rabble Rousing's primary effect of healing you on ability cast. While the self-heal from Rabble Rousing still applies, the anti-heal penalty from Vampirism significantly reduces the value of stacking additional healing sources, making this pairing inefficient.
