The mechanics are fine to most.it is nothing to do with lore but mechanics there everyone has to be crazy good to nut be wet cardboard level of useful in dnd it is oddly dumb.
Few have problems with PC halflings being Naruto Ukimaki and Rey Mysterio Jr.
The brought up in this game is that D&Dpurposely makes PC halfflingsout f sync with the rest of the race as the base lore is the boring part of a race designed for another IP copypasted to D&D.
Andd before someone says "they are not boring". Yes, normal halflings in the lore are purposely made boring and many like them that why.
And before someone says "I made halflfings not boring". Well that's the point. That 5e halfling lore serves the goals of very few.
Halflings are popular but few play or run as they are presented in the PHB. So the PHB lore is useless and should be changed. And so should the lore of halflings in many other official settings.
OR D&D should start promoting settings that display halflings as how people actually run them.
