Which of course is fine. Its not about the spell slot lol.
I know it's fine.
MTG Counterspell the card was bad design just like D&D Counterspell the 2014 spell was bad design.
BTW UU Counterspell was a cost problem.
2 mana counter any spell and put the card in the graveyard is bad design like 3rd level spell counter any spell and the slot is lost.
I will stress; this is if I don't have a magic weapon, which is the strawman argument presented. If that is the case and the DM is going to throw monsters at us that are resistant or immune to my primary weapons I will need alternative damage methods on hand, so I will make sure I have them. If I manage to find a magic weapon to use, I would cut the number I carry by a whole lot (I would still carry some), but without it you need this kind of stuff.
The issue isn't the resistances to B/P/S. That's upset over the easily visible.
The issue is that the fighter is a weapon specialist with a case of crippling overspecialization.
The supernatural martial is always over the DM dependence of treasure to counter the games monster design.
The lame 5e Hill Giant has over 100 HP and deals 20 damage a turn. And that's only CR 5.
The fact that your basic fighter with a longsword or longbow is dealing 1d8+6 twice against that on the regular is crazy. And not both longsword and longbow, only one of them.
And this is a lame giant with no special abilities and the fighter who is supposed to be the damage dealer of the party. Thus creating GWM/SS/CE/PAM as must haves as the defenses, offense,and special abilities of monster balloon.
Even WOTC who claims everyone loves 5e also says everyone hates GWM/SS/CE/PAM as must haves. And they are must haves because without feats or magic items, your fighter's damage is usually awful.And damage is all the 5e fighter has.
If you play exclusively low level or with 6+ party groups, you don't see this. But that's how this mess happened. The 2013 playtest focused too much on very low levels.
