Oh, I didn't realise that core player in DAIMP were so, well, core biased.
But in to the frustration. Actually, my three main problems are connection, connection and connection. I'm used to getting disconnected from host at stage 4 or 5 when soloing and getting used to massive lag that comes with few players (hopefully I'm not causing lag for too many others).
But really getting annoyed for connection problems while trying to jump to invited or friends games. 9 out of 10 tries ends to eternal load after failed connection. So far I know two ways to recover from this.
1. Try to join (through ps4 UI) to full game from other friend -> cant connect, lobby full -> jumps back to main MP screen where you can find or start game.
2. Restart game
It has been allmost impossible for me to join friends games or inv for 2-3 weeks now. Have to try other operator soon to find out if it is due strict NAT which I can't help otherwise, or is it just game.
Oh, and new players who are too embarrassed to stay in lobby when they die multiple times in a row and fade, when I'm training my level 1 characters there. You are welcome to stay and hang around there, you may learn something and at least you get XP. Yes, I kind of enjoy trying lower weapons and/or ideas with lev 1 in threatenig, helping new players is absolutily big bonus
Even more frustrating are new players with their 4-5 bars of life that jump to my NM run, which I've started solo just because I can't join/find games. NM for me with some character/enemy combos (not nearly all) is definetly doable, but not after few fade heroes.
