I generally allow 25m to compensate for lag, though I'll get a bit closer to mobs renowned for their blindness, like Tyranchas. There are also mobs that are easy enough to outrun that I may provoke a spawn of them so that no additional agro will lock on to me, but it took much trial and some epic failures to acquire that skill, so I wouldn't advise it.

Do not assume that you speak for all just because you are the loudest voice; there are many who disagree that simply have no desire to waste words on you.
