I have recently seen some uses of the tag attack. I believe this tag doesn't bring about any benefits, which, from what I understand, is a thing we want to avoid.
First of all, tags serve to help experts in a given are recognise questions that require their expertise. This, of course, cannot be considered with attack. Nobody can specialise in questions about attacks, not only since they are system dependent and the questions about attacks are so diverse, but also because specialising in 'attack' doesn't make sense even in conjuction with a system-specific tag.
Second, they help to find questions from the past. Unless you specifically know that there was a question with this tag, again, finding questions based on it is hopeless, especially with the inconsistency with which it is used.
Third, it is often too narrow and describes only a part of the mechanism, which, I believe, should be tagged combat. I find this tag more descriptive, unlike attack, and synonymising them into the combat tag would be, in my opinion, an improvement on this site.
Otherwise I fear that the attack tag is just an empty useless label added only in order to take up space in the tag department.
Any thoughts on this?
