As a Chinese student I often visited local Chinese and Taiwanese D III game forum and is happy to transfer what they have presented.
Most would agree that a 0.5-0.125 is over-nerfed and many of them who purchased Zunimassa set now even tried their WD and found more fun. This led to a serious problem about how efficiently WIZARD, as a class, farm A3 (as a farming standard). People who do not like a 120 second CD prefer not to take Archon with them, and purchase expensive gears that offer Cri Hit Chance to farm with CM/SC. This is simply because other builds cannot offer the same efficiency. Think of Blizzard/Hydra build, it is ranged and safe, but it is TOO slow and requires gears that provides life regeneration. Archon might also encounter problem when facing Reflect Damage elites and its survivability remains a concern.
This led many of my fellow friends guess how Blizzard POSITION WIZARD. What BLIZZARD wants WIZARD to be? It is a melee or ranged class like SOC in D II? If it is latter, then how come the AOE skills like Blizzard make people farm unhappily and inefficiently? The problem is not only CM/SC, it is other skills are too weak. A probable buff in SB is coming, but it is a melee skill. Without Crystal Armor or Ice Nova Wizard cannot even survive in A3 and how could you imagine players use SB? (Blizzard sometimes froze, but it is unstable. Just like investing in stock market, risk-adverse investors hate volatility and instability, same here) How about Meteor, when you find you use a star pact and fall into an enemy's body, how frustrated you could possibly be? Back to ET, on top of its proc coefficient, how much damage do you expect it to cause to enemies? Without a reasonable proc, nobody's gonna use it anymore. So WHAT IS WIZARD, a class farms relatively inefficiently compared to BB and WD?
The whole problem is not about a 0.5-0.125 nerf, it is about how efficiently WIZARD could farm. Currently in 104 with SC, to some high/middle-end wizard players they could farm efficiently. But if nerfed they might no longer be able to. By nerfing in a EITHER-OR way, Blizzard is in fact ruining this build and not really promoting diversity. In the worst case, if nerf, that's fine, but please provide us with a build that helps us farm at least as efficiently as WD or BB (There is a reason why BB is the first to reach lv 100...)
At this stage of the game, my personal opinion is that re-consider the proc adjustment and buff other skills. Don't ruin the existing build, do what you did in Hydra.
