Most of these "Super OP builds" are from faggots who seem to long rest after every single encounter so they can continuously drop their combo in every single fight. Which is much worse than even save scumming. Peak faggotry. This particular one requires you to just metamagic/sorcery points each time. But not spell slots so its a bit better.
Now playing my Dark Urge run after going through a good number of classes/combos. My favorites that let you not play like a faggot and can use up your rests/long rests as needed. In no particular order.
- Pact of the Blade Warlock -> You don't need to play like a Hexblade really. It's just a really flexible class that lets you do some range, drop some good spells that refresh on short rests, and do decent melee damage where needed. You can pick any race but since Gith has misty step and super jump in addition to Medium armor proficiency and martial weapons right out of the gate it puts you at a serious advantage in the early game. Also wrecks conversation checks with high Charisma/Deception/etc.(Gith being objectively so good is why previous editions would have given this race various penalties. Which isn't a thing in 5E)
- Battlemaster Fighter -> Just a rock solid really well designed fighter class that can fit in any group setup. Their superiority dice rolls and battlemaster maneuvers are just so good. Take Trip attack for general CC and take Disarming Attack too for even more! Riposte, Battle Maneuver that can help allies move into position without tripping opportunity attacks. Distracting Attack i found is even more useful because when you use it it puts all your allies into an advantage roll on the enemy.
- Multiclass 2 Paladin/10 Cleric (Tempest) -> Goes without saying that Tempest Cleric really seems to be the best one all around. Really good AOE damage and very tanky. Where the 2 Paladin comes in here is that you can, once per long rest, use Thunderous Smite to trigger all of the Tempest + Damage Wrath of the Storms stuff on top of eachother for one massive crit. Its really satisfying to use as you can get into position on boss fights then just drop the literal hammer on whoever.
- Multiclass Monk + Thief -> Still trying out this one but I really like it. Its a lot more fun than Barbarian. Tavern Brawler and such is built right into it but as I said earlier the Thief double bonus actions a turn is just busted in terms of movement. With monk you can get like 8 attacks in a turn THEN use your stupid mobility to run off where they have to chase you. You can also throw stuff just as well as Throwzerker.
- Wizard seems to be better than Sorcerer in most cases. Metamagic is strong but not as strong as the Wizard versatilities. Sorcerer is better for multiclass though in most cases. Also due to the Metamagic.
Berserker is okay but I never really found too much of a rhythm on it outside of using Frenzied Strike. I think Throwzerker has potential but you will need to play it very deliberately. Feels much more natural on Monk.
