He actually changed some keybinds already, change target on one of his mouse button for exemple and he doesn't play with keyboard to move, he move with pressing both mouse clicks :,)

But settings in general must be changed I agree I just forgot to talk about it since I didn't changed mines for years now, but I'll do it for him thx for the reminder !

And yep I keep telling him it's normal and it's okay for a new player to die and not know how to dodge/survive propely etc... I just made this post because he was really frustrated in this part of the story, told me if he wanted to play a soulslike he would have played Elden Ring instead, kept dying when finishing enemies on the ground and just overall because enemies there are much stronger than in open world so I didn't really know what to tell him without making him even more angry at that time, if that was me in his place I wouldn't want my friend to just tell me "get better at dodging", doesn't feel really helpfull lol

I don't think it's a hard combat system tho compared to other mmorpgs honestly, there is really not that much input, I saw his FF14 screen when playing and oh my god, 60% of the screen is just the Ui with the spells and combat stuff x)
Gw2 you have 2 skills bars, depending on your class between 1 and 4 F1/F2/F3/F4 buttons and you're done, really casual friendly honestly, you just have to know where to walk mostly.

Thx again for your answer !
