yes.all spells need to be redone, and fireball should NOT be better then other damage spells. Now the argument can be made to bring other spells up to that level, or bring it down. Same with Meteor Strike.
I also want hold and tasha laugh NERFed to heck... there is NO amount of damage is equal to "take a turn or more away from target" let alone "Take a turn away AND debuff target"
a 20th level wizard running into a non legendary 20th level threat can use a 1st level Tasha laugh spell to more effect then any damage spell. Heck since saves don't go up with level if facing a target with low save it may just knock them right out of the fight... compare that to any damage causing spell.
no 1st or 2nd level spell should be powerful enough to negate a threat like that
1st and 2nd level spell should have levels of debuffs in range of:
halve speed of target,
inflict disadvantage on attack and/or saves,
prevent spellcasting except cantrips for one round,
"weaken" condition: all damage you deal is halved,
have attacks gain advantage vs target,
targets provokes AoO,
