No offense, but you thought polearms were DEX weapons, a category that doesn’t even exist in 5E. Your opinion is not well informed.
Finesse weapons exist...and they are essentially DEX based weapons geared toward classes with high DEX because they use DEX modifiers. Daggers, crossbows etc. You can technically say they can use STR modifier but you will never see a crossbow or dagger wielding barbarian. For all intents and purposes finesse weapons are DEX weapons for DEX focused classes like Rogues.
