There's also lots of things that are more easily hit by force effects than by physical stuff.
At higher level. This thread is about levels one to four. It's rare for a foe to have weapon damage resistance at low levels.
Mostly, though... If you're looking at damage, you're usually playing wizard wrong. I'd guess that I did points of damage in at most a third of my combat rounds in our entire Pathfinder campaign, and I was devestatingly effective. Damage is not the wizard's strong point, and comparing their damage to a rogue's damage is like comparing their hit points to a barbarian's hit points. Wrong metric. Wizard's about reshaping combats, not hitting things.
Like I said in my earliest posts here, show me.
Make a list of cantrips that can be used 2 rounds out of 3 to shape an encounter because cantrips at low level are the wizard's bread and butter.
Show me a lot of spells that affect the outcome of an encounter as much as the Fighter does, or the Cleric does, or the Barbarian does. Sleep is practically the only one. Even illusions like Silent Image are relatively non-practical most of the time. Sure, you could create the illusion of a creature to distract enemies a little, but the creature doesn't make any sound. It doesn't do any damage. That attacking fake beholder is cool looking, but ultimately disbelieved when the first NPC arrow flies through it. Yes, the wizard stopped a single attack. He spent an action and a Delay spell to prevent an action. Status quo. Hardly memorable in the tales of yore.
It's one thing to claim that low level wizards reshape combats on any consistent basis, it's another to illustrate it.
For your POV to have any teeth to it, you have to show what you mean. Give a half dozen examples where the Wizard comes anywhere near reshaping a combat. I'm open because I cannot find such spells in the PHB. At level one, Sleep is the main one. Fog Cloud often harms the party more than it helps them.
Hold Person. One round average. It can reshape the battle if the situation is such that the BBEG that it is worth casting on, fails his save and is in range of most other PC attacks. This assumes, of course, that the BBEG is humanoid.
Web is fine. Not great. But fine. Foes get out of it fairly quick (some are not significantly slowed down at all).
Suggestion? Limited, but it could have one foe leave the conflict (but not attack his ally). Or not if he saves or if the DM rules that the suggestion is unreasonable. One has to really get to second level spells (with the exception of Sleep) to get to the point that the Wizard can even contribute a few times a day, let alone reshape the combat.
Sorry. I don't see it. Please show me the spells that I missed. To me, Color Spray, Charm, and Shield have been nerfed since their 3E days. As has many other spells.
