Q34: Please implement a DPS tool and a feature that shows a monster’s HP %.

[Viridiana]

In this scenario, do you need a dps meter?

Somewhat irrelevant. You made the statement that:

If the boss doesn't die, -everyone- needs to dps harder. Yes, even you.

Unless what you actually mean is "If the boss doesn't die, that guy who sucks needs to dps harder." But that's not what you said. So, which is it? Do we need to struggle to carry people who suck, or does everyone have an onus to play to the best of their ability?
