Let me start this post off by explaining that this not supposed to be a ‘rage’ post about the expertise system just the imbalances I have found with it compared to other stats and the way these imbalances play out. The problem I find is that there seems to be no significant diminishing returns for the Expertise stat. Following is a list of a few stats, the graph that the stat follows, and the R value to show how close the graph fit the data points (10-13 per stat.) Now here is what I found out.
Expertise y = 0.0229x + 0.3329 R=.998
Critical y = -2E-05x2 + 0.0433x R=.9998
Surge y = -3E-10x4 + 5E-07x3 - 0.0004x2 + 0.2012x + 0.0166 R=1
Now you may be asking what this means, the expertise graph is linear, meaning a steadily increasing amount in the percentage that each point applies; but with crit and surge the more points you put into them the lower the benefit is. With the diminishing returns being as low as it is and the way the stat applies in game that can lead to several disparities in damage output. For example a player in full Centurion gear (lowest of the three gear sets) has 469 expertise which translates roughly to 10.5%. Now this is a 10.5% “Damage boost on players” and a “Damage reduction from players” leading to a 21% damage gap between people with little to no PvP gear. Excluding the benefits from the other stats, you can start off a fight automatically doing 20% more damage to someone than what they can do to you; with an advantage like that my 5 year old brother could manage not to lose. Now I understand getting expertise gear will negate this advantage I am pointing this problem out for those who just hit 50, have bad luck getting gear, or simply only like to PvP every now and again.
Now this is where I leave this question up to everyone else, “What should be done?” Should the expertise system be scrapped, unchanged or just simply reworked? I believe it should be reworked; PvP gear should give you an edge in PvP but I feel a gap in damage as large as this leads to gear deciding the victor and not the skill of the player. Feel free to post your ideas on this matter I would like to know if I’m the only one who feels this way.
