Agreed ^^ I look forward to the final phases of t10/11 a lot. "Do I need to soak or not?!" "Are tethers on tanks?!!" As brd I also enjoy how redfire has a total life of it's own too in 12, similar case with flare star in 13. I also really enjoy ramuh w/o TS or marked party members .
SE have proven that they can stress the player with just random elements of minor chaos within scripted fights. While I think most players enjoy these, I'm not sure I'd want more than I'm currently getting.
