Nah. The sole problem is on-hit effects affecting more than one target. Make damage and on-hit effect only affect the first beam and it's fine no matter how many attacks there are.The fact that eb has multiple attacks rather than working like a normal cantrip that just adds dice is the big problem because everything including +n wands get multiplied & if a gm introduces anything that changes how cantrips work eldritch blast needs a special carve out because it's a force damage fighter extra attack heavy crossbow+crossbow expert that scales with character rather than class level
Multiple attacks don't really matter and attack bonuses don't really matter because the damage is split up. Sure, with multiple attacks you're more likely to hit once, but you're also more likely to do miss at least once so you're much less likely to deal full damage. Since wands of the war mage, rods of the pact keeper, staff of power, and staff of the magi only affect attack rolls and not spell damage rolls, I don't really consider them a problem with EB. (Not like the last two are a problem due to their ability to boost cantrips.)
A cantrip at level 11 is supposed to do 3 dice worth of damage. It doesn't matter that much spreading it out. Having +12 to do 3d10+5 is not much different in terms of damage output than 1 attack at +12 dealing 1d10+5 and 2 attacks at +12 dealing 1d10. Sure, you can invent contrived situations like attacking a mass of mooks with 5 hp, but how often is that a problem at the levels where you really have a lot of beams? And how often is cloud of daggers or acid splash better in those situations anyways? And how often is the fire damage type better or chill touch rider better or higher damage of toll the dead or debuff from mind sliver better, etc.?
It's not EB that's abusive. It's this insistence that EB invocations trigger on every beam hit. Unfortunately, since the class is otherwise pretty hamstrung as far as spellcasting, giving the class a cantrip that outclasses everything else was what the designers chose to do.
