Is it just me or has anyone else noticed that D&D characters stand too close to each other?
Time after time over the years players act like their characters are moving in tight certain formations that never vary (except of course for when they are grabbing some loot "secretly"). It gets sillier in the wilderness when parties with some on foot and others on horseback of all different sizes, background, and encumbrance all keep close together in a fixed formation.
Has everyone forgotten about flaming oil, sleep spells, fireballs, Lighting bolts, web spells and the like? The closely spaced "special ops" marching in fixed position is asking for a TPK.
Space the party out and it should be darned rare for any of the attacks mentioned above to ever catch more than say 2 or 3 characters. Real world military forces space folks out so a single grenade, mortar, land-mine, or machine gun doesn't ruin everyone's day.
So should DMs reinforce sane behavior by pointing out the folly of the players ways or TPK adventuring parties until folks catch on?
