So,
I played Diablo 3 Ultimate Evil Edition on my Playstation 4 console.
I got Crusader 70lvl with ~120 Paragon Level.
I did story killed bosses did quests and maxed to 70lvl.
After that i did some rifts and got like 120 paragon.
I wear items i found droped from monsters, unique set and rares.
I dont know how to craft items but i got in stash some things droped from monsters to do it i think..^^
My questions are this ones:
1- Can i play online without PS Plus this game with other people like d2 battlenet is playing?
2- Can i reset my Stats Skills i made during playing the game, like in d2 where it is possible, or is it permanent amd i cant change?
3- Can i trade with other users so can i get some really Gz or Best gear for my Crusader? How does work trading items in d3 ps4? I dont need any hacked, i need 100% perm gz items for my Crusader

Ty for this 3 questions friends.
I really just played story, leveled Crusader to 70lvl 120para and thats all, i dont know game system much.. ;D
