I don't think a new arbitrary class would help, you need a class with a working JS behind. The "advanced-tooltip" class works with the dev-wiki tooltips feature.

Also, I highly recommend not to use !important anywhere unless you are forced to. A lot of !important statements will get you in bigger troubles than the ones you tried to prevent, and it is also mean toward other users who'll have difficulties to make personal customization.
