LordVyreth said:But 48 commoners transform into a 30 HD creature with hp equal to all the creatures combined? That strikes me as a little ridiculous.
That was my first impression, too.
However, some of the powers of a barbarian who has fought alot of battles are pretty ridiculous also. Experience in battle appears to translate into an ability to resist charm spells, fall off of cliffs, and a whole bunch of other things. If you can accept the game logic that says that experience translates into all of these heroic things, then why not accept that a large group of persons with determination can achieve great things collectively?
LordVyreth said:A decent fighter would theoretically take off 2% of the group's total combat effectiveness per hit, or 10% in a full attack.
According to what theory though? According to DnD without mobs. Mobs certainly don't make sense as simply a "record-keeping" technique for lots of characters - I would see them as an entirely new thing - an advantage to large groups of creatures banding together where, due to morale or whatever, the group of creatures becomes greater than the sum of it's parts.
LordVyreth said:I mean, the only real value of Cleave, Whirlwind Attack, and evocation magic at this point is takign out mooks, and this would completely nerf all of them.
Can you attack individuals within a mob? In this post some mention was made of killing individuals being equivalent to negative energy levels. And also double damage from area spells?
LordVyreth said:Oh, Lonny, I just realized the chaos this could cause if the PCs try to turn it about. Finally a really effective combat use for those hundreds of 1st and 2nd level followers you get from Leadership! Or they could just gather a few dozen beggars and use Diplomacy to incite them. I'm sure somebody here remembers the infamous "beggar mob" stories from Knights of the Dinner Table.
Taking a look at the "mass combat" thread on this board, there's some reasonable arguments that low-level mooks are such a joke that they wouldn't even factor into wars in DnD. Calling it "chaos" might be overstating it somewhat - in fact, your post sounds strangely reasonable to me that there would be an effective use for followers. Keep in mind that normal supply and deployment logic would have to be considered before you marched 500 followers into a dungeon. And IMO there were plenty of reasons to want 500 people in the front rank to set off traps - before there was Mob template If you didn't have to deal with this issue before as a DM, I'm not sure why anything would change now.
