1. Pinging.
There does need to be something that indicates that a particular part of the background is actually functional and not just decoration. And you don't want to have the "hey look, item here!" glow always on because it's kind of ugly. I preferred being able to just hold the ALT key to pinging, though.
2. "Gamer vision"
Doesn't need to die, but could probably stand to be less frequent.
3. Patches
Nah, patches are good. If anything, looking at PC games, I feel like we get less after release support than we used to, probably because certification makes patches expensive. I can see annoyance at Day 1 patches, but given how long it takes to get a game shipped, they seem logical things to exist.
4. MoBAs/ESports
I find it all surprisingly easy to ignore
5. Buying in game currency with real money
Yeah, that's horrible. Particularly since it makes them likely to work against modding and cheating.
6. Skimpy armour isn't really a "trend", is it? I mean, it's pretty much always been around and if anything it seems like there's a slight trend to sensibly clothed female characters. But I could certainly stand to see less skimpy armour.
