Being able to clear something that someone else is able to clear is not the same as being on a level playing field. A group not using food or pot buffs might be able to clear the same content as a group who does use them but objectively the group using all the tools at tgeir disposal has an advantage over the group who does not.
You are mistaking equality of outcome (clearing a particular instance) with equality of opportunity (having the same tools available to use as anyone else with the same goal as you) and these things are not the same.
I said at the beginning of this exchange that it seemed as if you didn't understand what the word disadvantage meant. After this all I feel like that is still the core issue here. You could argue that not having parsers does not cripple PS4 players, you could back up that argument by finding a group of players clearing Savage content with absolutely no parsers involved but what you can't argue is the objective fact that walking into any situation with tons of less information than you could have is disadvantageous. If you want to try to simplify this into something that suits your narrative all you have to do is ignore all of what I've said and also basic definitions of words that elementary school children understand.
Antecdotal and easily dismissed. Please bring something other than " in this other game someone was mean to me!" to the table if you're trying to make a point, the problem is your opinion isn't worth any more than another GW2 player saying it isn't toxic which, if I'm not mistaken, has already happened.
Anti parser crowd I'm still waiting for any factual argument against official parsers - not that there is one but let's see what you've got.
