I completely understand the frustration. I can react like this aswell, but once my initial emotional reaction is over and i start to think rationally, i can see the mistakes i made or things i could of done better.
Some players do die more from the infamous skaven rat more, then when there is a boss + horde + specials. I’m sure everyone had this happen to them, where you fight a little group of skavens and mis timed an attack an died. I don’t know what it is, might be that when there is not alot of enemies, players start to pay less attention. Happens to me sometimes.
The issue of bad fighting places or your team not listening to voice commands Will always exist. Some things i try is to use voice commands first, while moving or already standing where i would like to stand. But if i see my team doesn’t react then i go join them and try to make the best of it. When i see it won’t work out i premtively use a bomb or potion.
Another thing is when players start to split, maybe because they are tunnel vissioning on enemies and don’t pay attention to their team (which happens to everyone sometimes), i try to notice that and move with them, or protect their back, without putting myself in too much danger ofcourse. It’s not always worth it to go help someone very split if you have a big chance to die yourself. Pushing as a team is best, but that is difficult in qp.
Basically what i’m trying to say, is that if you are or think that you are the better player in the group, try and see if people follow you, if they don’t, you follow them and try to make the best of the situations you get put in. Knowing priorities and such are important aswell. Another thing is that if i notice my team not being the best, and they are all on shade/bh/huntsman etc, i try to go on a support/dps career, so i can support my teammates and win, rather then Force a squishy class thats more difficult to help my team with if every one of them already is dps. So identify what your team lacks and try and pick a career that fills it. For example, mercenary is a great ‘qp carry’ career. Except if everyone is tank, then go a shade for example.
I know it’s annoying, and sometimes you just wanna play what you like in qp, and sometimes playing what you want can work in bad teams. But basically try and carry them and support them, try not to be arrogant and make it sound like you are above everyone else, if your entire team goes to that spot and doesn’t want to move, fight with them, etc.
( Not implying you don’t do those things, just some tips)
Also for some players, fighting a horde is pretty overwhelming. So don’t be to harsh and the secret to playing quickplay is: lower your expectations.
If you have been playing with a certain type of players alot you start to except basic things, but we have to remember not everyone knows these things, and that we all started from somewhere.
Also changing the mindset and being more interested in the moment and not about winning will help reduce getting mad quickly, if you are someone who leaves quickly. (This doesn’t mean you cannot get annoyed)
Hope some of these help. If you are interested in doing higher level content, try and find premade groups on existing discords/reddit etc
Also touching on this topic in general.
Improving the wiki can be a great starting point. Yes some basic things should be in the game, but being able to reliably fall back on the wiki would be great for new players.
