No those are the players that can't even solo a 70 and claim that they have played d3 a lot. Sorry but no.
The problem is that they are not PoE players ranting about other games. They are actually Diablo fans that have grinded this game a lot and eventually decided to quit because of lack of new content and gameplay issues. They switched to PoE, WoW or any other game and they are giving their opinion on the current state of D3 after experimenting other things. I haven't ever played PoE but i might just try it out.
Listen all you have to do is look at my armory. I've played WoW as a hardcore raider for some time before i quit that game, I played d3 and made top 10 in S3, S4, and s10. Not many people I have come across that talks smack D3 is a good player that had switched to PoE. This is simply false.
They're not giving opinions they are being bigoted and hateful towards D3 players for no reason. In this the general public of PoE are simply children. Like i said I have played both games and played them well and i have experienced both communities. If all you do is go to a Diablo fansite and bash players and a game, maybe you should direct some of your free time to the game you're actually playing and then those people would probably be better players and people.
There is a massive difference between D3 casual play and D3 competitive play. Only people who play for leaderboards and push in group grifts know this difference. There is a huge difference between grift 60 and a grift 105 solo. Not only in terms of how good your gear is but how you approach the grift.
