A decade ago the MMO genre tended to favour quite complex game systems. It is what the playerbase expected and allegedly preferred. But tastes and prevailing trends change over time. Plus game developers often see a change in staff and alterations in their creative visions. Hence over time, game systems can become unwieldy, esoteric and frankly annoying. So when a decision is made to refine, rationalise and improve these systems, it can be a complex task to undertake. Furthermore not only are there the practical and logistical realities of having to tackle ageing code, there is also the choppy waters of community relations to navigate. Because regardless whatever you seek to change, there will always be those who will oppose it and consider it an outrage perpetrated upon them, comparable to the Peterloo Massacre.
