Honest opinion- You'll be more "useful" as an archer, since in PK assist-attacking targets is key to being able to come out on topHowever, when it comes to actually having more fun? Without a doubt you'll enjoy Psychic more. I used to main both of these classes, and they're completely different playstyles without a doubt- however I felt that when it comes down to it, I enjoyed Psychic more simply for the fact you have so much versatility.For just playing solo, and playing for fun, Psychic without a doubt.
find other game is best way of playng epw
Welcome,hope u enjoy ur stay.i dont know much about psy,but i am pretty sure archer would be best option between these two for mass.ArcherPros: best range,mobility,highest phys dmg,can deal fairly good phys+mag dmgCons: squishy,kite(more than some other classes)Psychicall i know about sage psy is that the heal purify.not sure if there is any other pros/cons i forgot.feel free to quote if i forgot something.
tl;dr :Archer are AWFUL until you dump a lot of $$$ into attack gear + defense gears
