Of course there was a chance. The odds were against it but it wasn't a million to one odds or anything like that. Rolling a 2 and a 3 (with a higher dex) vs a single 5-6 isn't that impossible, particularly when it's 2-3 people doing the rolling of the two dice versus just one foe rolling the one die. Someone here I am sure can calculate the odds but it was definitely doable.
I think you will find the chance being lower than you think. But anyway, the point is that I disagree that in increases "drama".
Although now that I think about it, it is a matter of opinion and personal preference anyway. So I guess it is fair to say it increases drama for
him and others that think like him, but it does not increase it for
me. So to each his own?
Name a bonus action that doesn't have the same issues as two weapon fighting? Polearm Master where you can attack with the other end of your polearm? Casting a cantrip and attacking? I don't think two weapon fighting is the exception to bonus action issues, it's fairly representative.
Those aren't issues. That is Bonus Actions working as designed. The whole point of Bonus Actions is so that you don't start stacking dozens of "free" actions on top of each other.
Bonus Actions mean that you can't get a Standard Action attack, then get an attack from your polearm feat, an attack from your cleave feat, cast a Bonus Action Spell, and Dash with Cunning Action. That is why Bonus Actions were made in the first place and limited to one per round.
The only "problem" with them, and the one that Mearls brought up (the only one that
anyone ever brings up), is that it isn't broken to allow a character to get two attacks with two weapon fighting and then use a Bonus Action to do anything else. But instead of just saying, "Well, we should allow two weapon fighting without a Bonus Action then," people, including Mearls, say "Oh, I guess Bonus Actions are bad design."
What? How does that follow? Just because there is one thing that was listed as a Bonus Action (okay, probably more than one) that shouldn't have been, doesn't make the whole Bonus Action system bad.
Now I'm not saying it is impossible to replace Bonus Actions with something better, but I am saying that replacing them with hundreds of unique actions is definitely worse.
