I use it now for 1 week and it works great, I leeched 600k+ honor and made 60% of pvp rank 11->12 (standing was 9th).
But I more and more start to worry about suspicious people, it just does not look good, if you have such an amount of honor and something like 200 kills ;)
It also is very likely people will notice you're always standing in the AV tunnel day and night - with zero kills, zero deaths and a crapload of bonus honor. Since 1.12 it might seem less likely, but especially if one is in a huge guild, there will always be people thinking and asking.
I consider to start keeping a lower profile, either run it only during night and make some alibi kills during day, or roll a twink, bring him to level 60 and then bot him to pvp rank 14 - without worrying about a huge reputation loss for my main among my realm and especially my guildies. I also think, I'll be using the TB Battlemaster instead of the OG one, less people there.
But the tool/idea is really great.
One more advice: if you already have a high rank, don't enter the bg as soon as you can (I don't use this tool to enter the bg, but rather a simple autojoin addon instead (sspvp in my case, the same for leaving bg), or else you could be selected leader of the raid by the new battleground grouping system.
Very bad thing if you try not to be noticed (everybody will whisper you to move him to some other group, horrible, especially if you are not there^^).
What do you guys think - what is the best method to do the anti-afk routine - move/rotate the character or jump, send chat to a private chat channel, or maybe running an addon command (open ct menu or the atlas ui)?
The first seems to be too easy to notice, the second could get logged by blizz, I like the third.
