Hmmm... 6d10 for moonbeam if upcast to level 3 vs 8d6 fireball one time...
I'm failing to see how moonbeam isn't OP in its current state. The issue with moonbeam is that it hits targets twice, once when cast on your turn and again on the targets turn. It should not do this. There's no way they don't fix it on release. It's brokenly OP.
Since you are failing to see it, let me help you, with math.
Druid MB: 6d10 have an average of 33 as an outcome, but since AT LEAST 50% will be saved(CON ST), that mean an average of ((1/2)*33)+((1/2)*16,5) = 25 (rounding UP).
So, an average of (25) damage using your concentration AND your action.
Sorcerer TwinHaste: Currently it is giving a full action, so on a Barbarian/Paladin/Fighter/Ranger they are getting two extra attacks. With a Damage Dealing class you can EASILY achive an average of 15 damage.
So an average of 4x15= (60) Extra damage using you concentration but WIHTOUT using you action. Meaning that if you add a CANTRIP on top of it that already a (71) damage, and that is not even considering the increase of Move-speed, AC and DEX ST of the party members buffed.
Cleric Spirit Guardian: 3d8 have an average of13,5, since it is WILL ST most enemies won't resist but let PRETEND that 50% will resist ((1/2*13,5)+((1/2)*6,75)) = 10 (rounding down).
So an average of 10 damage PER TARGET using concentration but without using your action. Since SG area move with you its easy to hit 3~4 targets on a turn, but even if you hit just two you still have your attack which pretty dam sure will deal more than 5 damage as an average, and that is not even considering the slow that SG área impose on enemies.
Lastly Fireball: 8d6 have an average of 28 damage, but since... ... ... ... ... that means an average damage of 21. But fireball have a REALLY HUGE área, you can easily hit 4~5 enemies that means 80~100 damage. So, you need 3 to 4 turn with Moonbean to reach this damage. So you can argue that MB is more Cost/Benefit damage wise, but you need to consider that in most case the burst of damage works better since you remove enemies from the field, and you can add on top of that the fact that fireball does NOT use concentration.
Conclusion: Yeah, MB is definitely better than Call Lightning currently, but that isn't because MB is OP but because Druid spells is UP... Not to mention Wildshape that is currently a JOKE, and no the problem isn't the fact the Land Druid have acess to some WS but the Fact that ALL WS s..k hard.
