Mana Wrench needs to stop being harped on. Yes it's strong against casters but it does absolutely nothing against warriors and rogues. Admittedly it does help to turn the tide of battle by stopping outgoing heals from the enemy team and ensuring that you have mana enough for a shield, but the moment a warrior or rogue looks at me while I'm playing my dominator and I can't polymorph them... I'm dead. Yes, it does tend to wreck casters but that's why you have a team in a warfront so that 1 dominator doesn't win the match against you no matter what you do. If you have a problem with a dominator point them out to your melee counterparts. There's no reason for you to randomly run off KNOWING that you're not going to have any mana and attempt to kill them by yourself.
