well, i've been helping out in the TA quite often for a year and a bit now, and you do get lots of these guys at times, usually bratty little kids with no clue, best thing is to ignore them totally.
infact, i secretly impersonate an officer of the trainer corps at times to keep them in line:p making bold empty threats at the kiddies usually gets them to die down or leave lol.
anyway, beyond the brats, helping out in the TA is some of the best fun in AH. i've made most of my friends in there and you have plenty of decent fights while also being able to help people out and share your knowledge.
everyone should try the TA out a lot more, nothing more rewarding in this game than teaching.
those who can, teach, and it's worth it!
it would be really great to see a few more of the sticks from the MA stop by the TA and help out in there, an expansion of the trainer corps would be really great, especially for the upcoming release of CT
