I think the biggest problem is that it says "intentional". Almost nobody intentionally aims at you and hits you, and if he does he needs to get banned from this game. On the other hand I like to press M if I for example dehorsed a cav, go in for the kill and some xbow shoots me. Of course he wasn't shooting at me intentional, but everybody would agree a report is justified. That is why the word "intentional" becomes meaningless and many start pressing M on every occassion.
How about "reckless"? (also big plus: 3 characters less)
This is the problem I have with the system. I noticed the message says to hit M if you feel the team hit was intentional, however I've seen admins message that you should only report for intentional
or reckless hits.
If the system is only for intentional hits then it isn't solving anything (if someone
intentionally teamhit 5 times in a map they deserve much more than a kick/20 minute ban...they need to have an admin step in). If the system is to curb reckless team hits then it has potential, however defining what is reckless hits versus legitimate mistakes and asking the cRPG population to properly tell the difference is an exercise in futility.
So when I see people saying "this system is great people are actually careful with their swings in melee now!" you realize that the way the report is worded right now... people reporting in that manner are actually using the system incorrectly, right?
