As with all updates, it seems like there are advantages and disadvantages to this one. Judging by the amount of posts on this thread, this is a very controversial proposal.
For me personally, I do not wish to see the full Grand Exchange/automated trading, simply because it will make the game substantially easier. Part of what attracts me to Old School RuneScape is the challenge it presents. Bringing in the Grand Exchange will remove that challenge.
As such, I'll be voting no to any form of automated and offline trading. I do like the idea of sending trade requests through the trade post, though. That seems like a nice compromise.
