Zader or zaul

Zaul is proving to be meta on my shard. I just use maul with palp, and the rest are tanky characters nobody wants to hit. Zaul forces the enemy to be at the mercy of your stun rng, if you have some good mods. My palp is moving at 275 right now, and it's a thing of beauty. Zader is better for raids, and in arena if you can get tfp faster than your Zaul palp. It's a question of modding and if you wanna succeed more in raids, or arena
