There's a difference between me trying to choose between the Berserker and Totem subclasses and probably choosing to go with Totem since resistance to energy damage is marginally superior to getting an extra attack per round in one combat per day, and the official developers of the game officially declaring that the Berserker subclass is a garbage subclass for idiots and absolutely nobody should ever play it unless they're intentionally trying to make an under-powered character.
If the Zealot is supposed to be Berserker 2.0 because the original Berserker is considered unplayably bad, then that's a problem. That they choose to hide it as a stealth-upgrade, rather than address it with errata, does not make it less of a problem; in either case, it's bad enough to require an official fix. There is no positive way to spin this issue, if the Zealot is supposed to replace the Berserker.
If the Zealot is not supposed to replace the Berserker, than that indicates the developers still have some confidence in the Berserker; it may be less popular, but they still think it's good enough to be fun at the table. In that case, and that case alone, the introduction of the Zealot is not indicative of a problem with the product I already own. The disparity may still exist, but it's not so incredibly insurmountable that they feel the need to address it with an official patch.
