Yes. Or, rather, under the paradigm of new runes (meaningful choices that influence playstyle and require at least semi-concious thought), Fervor does not fit anymore, being a stat stick boost that is always on, not influenced at all by your decisions.
And before countering that Press the Attack or Lethal Tempo are equally brainless - no, they are not. Both of these keystones have at least a modicum of thought involved:
- PtA requires three auto-attack hits - and, with the PBE nerfs, you only get the damage on the third hit. Only the fourth auto would be influenced by the damage boost. Furthermore, unlike Fervor, you are committed to a target by its effect - if procced, you only get the damage boost against a single target, and switching to a different target prevents you from stacking up again till the effect falls off on the previous target.
Now, you can definitely argue that it might be brainless in a 1-vs-1 lane, and I'd give you that.
- Lethal Tempo is restricted by its delayed activation (1.5 seconds till activation, which can mean a radically different situation) and the fact that it has a cooldown (6 seconds on PBE).
The only keystone that is similarily no-thought-required as old Fervor is Summon Aerie, and I fully expect even more nerfs there. Oh, and Kleptomancy on certain champions (cough Ezreal cough).
EDIT: And two reasons Fighters suck vacuum right now: First, for some of them, their theoretically most synergistic Keystone is gated by being associated with stats that don't particularily benefit them early game (PtA comes to mind, for all the attack reset types save Irelia and Jax). Second, the new rune system's focus on damage means that, in a 1-vs-1 laning situation, champions that can build/feature early durability are better than those that need to build damage (because both offensive power and defensive power are factors in total strength, and factors = multiplication. 1.5 defense value x 1.5 offense value > 1 defense value x 2 offense value).
