If you want to continue with this, fine. But hyperbole, lack of evidence, and a disregard for the rest of 5E's mechanics won't get you very far.
Let's get this out of the way. I've been nothing but respectful in each and every post in this thread and on the boards at large. So why this veiled aggression?
Okay, let's continue.
You're right, that was a typo. It's 40 damage every round over 5 rounds, for a total of 200 damage. So I was off by 10, not by 50 like you are. And I did this with a freaking calculator just now so I don't know how on earth you got 150.
Let's see... Ranger. Two attacks per round.
Attack 1: d8(4.5) (weapon) + d8(4.5) (colossus slayer) + d6(3.5) (hunter's mark) + 5 (Dex mod.) =
17.5
Attack 2: d8(4.5) (weapon) + d6(3.5) (hunter's mark) + 5 (Dex mod.) =
13
Damage per round:
30.5. Damage over 5 rounds:
152.5
Where did you get the other 50? It's possible I missed something.
Would you mind doing me a favor? I've been providing you with my math. Would you mind showing us how you got to over 250? I believe it, I just want to see it, in fairness and all.
Okay. Fighter. Four attacks per round.
Each attack: d8(4.5) (weapon) + 5 (Dex mod.) =
9.5
Damage per round:
38. Damage over 5 rounds:
190
Both of these calculations don't include magic weapon bonuses (by level 20, +3 probably) which brings ranger up to
182.5 (10 attacks with +3) and fighter to
250 (20 attacks with +3). All of this without a single Superiority Die nor Action Surge spent. If the fighter were to spend his top potential in those (sure, not in every battle, but in important, big battles, if the party is likely to take a short rest afterward to collect themselves, why not? Will he hold back while party members die around him?), he could dish out
320 (using 1 Action Surge (50dmg) and half his SD (20dmg)) to the maximum of
390 damage for both AS and all SD.
...doing max damage each round is 300 damage...
Huh? Why would the ranger be doing max damage?
Ah... this has gone completely off-topic. I didn't intend to bore everyone to their deaths with all this. My point wasn't to pedantically debate every pro and con of these classes, but simply to ask you guys if it would be better for hunter's mark not to be tied to concentration (and ideally to take it out of the spells completely and transfer it to core martial features). For reasons of flavour, overall damage, etc.
