It's infuriating when it takes like 10 minutes to load you into the match and by then the room is already full so you have to leave that one and join another, but the time it took to load you into that room was already wasted.
I find it unfair how in some matches the level range is something like LVL16-40 and as a low level player I jump into one because there's no other game that isn't that so I just get exploded by the higher level guns and can't kill the enemies because even if I deal 100 damage, they just have the +HP perk or have already killed me before that happens, and thus they survive the fight and I die every time. It's just so difficult to play against higher level players, especially when the level range is LVL16-40, which is pretty unfair for the LVL16.
