yes i used some hyperbole.
the point (and the problem) still stands
also at level 5 goblins are obviously a joke to fight and many enemies you'd fight in high numbers would have more hp.
spellcasters also will probably still be strong because at high level their power-level increases much more than martials'. they just wouldn't use damage spells if the hp bloat continues.
and instead of fireball (which is overrated anyway) they'd pick hypnotic pattern or fear as a 3rd level spell.
and now that you say it i wonder if they are going to change fireball like firebolt.
