Only Zenyte items, Cerberus boots, Bandos and Armadyl are a problem in the current economy, though not to the extent some people are exaggerating. That is, of course, to be expected when you have a server that has been running for over a year and when there are multiple ways to obtain those items (BM shop). Essentially, a sink for those items would have a much more positive impact than a reset. The updates to the Wishing Well were a good start.
Honestly, most people who are begging for a reset are only doing so because they have 20m banks after being cleaned at Duel Arena.
