No other warlock nerfs are planned for 2.4. One of the things we look at is class representation in arenas (although normalized for class popularity). In this particular chart, a value of 100% means the class is represented as we'd expect, a value over 100% means the class is represented that much more often than we'd expect, a value below 100% means they're represented less than we'd want (obviously this chart doesn't include a spec breakdown in any way).


one other detail regarding the chart, this one is set at 2200+ rating.

Locks are doing pretty well overall, but what had us worried was that it appeared to us a month ago or so as though warlocks were on an uptrend. However, the evidence is strong that that trend is reversing, which means significant nerfs aren't really what we want right now (we really don't know where those numbers will settle down).
