I have been using one of the teaching ROTS chats the last couple of days and finally got a kill yesterday after about 6 tries, though I was never the first to die in any of them. I'm really glad I did it and learned it as opposed to just leaching it, far more gratifying! I was very hesitant about it before and wrongly assumed people would be elitist about learning and joining a team. But the guy teaching in the chat went way above board explaining tips and tricks before we even tried it.
If anyone's worried about giving ROTS a go as a team boss, don't be, there are plenty of people out there to learn with and learn from.
Now I just need to take down the big guy, I hope the chats are good for that too, the only one I can see on the forums currently is RagoPvM so I'll give that a go this week.
