Agreed, which is why we need to inteperate what they are concerned about and eloborate on it, instead of the so many disparaging comments here targeted at the people that have concerns.

Why not then attempt to address the issue with further constructive comments such as:

Instead of tab targeting, wouldn't it be better to have all players targeted, but only targets within the retical will be affected by your actions.

Thus enforcing the skill based playability immersion while offering a solution to identifying targets and improving sociability.
