overall though melee is really better. sure a spell caster can drop a group of inconsequential enemies really quickly, but they are severely nerfed on bosses. the trash enemies normally wont be able to kill you anyhow, and just picking up a few points of hydro will give you healing, and with melee you can dominate the bosses.
Agree with this. Boss design in this game is awful because they're practically immune to so many things it just makes them "tank and spank". My duo lone wolf mages just spam summons at many bosses because I CBA trying to lower their resistances and chip away at them with elemental spells.
There's also death punch, but eh.
On the one hand, I totally see what you guys are saying. On the other hand, I can't think of a boss in this game which doesn't also involve a "group of inconsequential enemies" to simultaneously annoy your party. So I don't feel like "boss design" is awful; instead, you just have different roles for different party members in boss battles. Spellcasters neutralize the chaff (especially against bosses which respawn dead minions, which is a fairly common boss design theme), while melee deal with the Big Man (or Woman, or Thing).
Plus, like you mentioned, casters can always
create attackers to help deal with the bosses.
