Opinions are opinions,what arguments weight more strongly for one might weight less for others. Anyway a summary of this post is at the bottom

.
A simple list of facts is
Positives:
- Zoom makes it easier to fight at realistic ranges
- Zoom makes it possible to have realistically sized maps
- Zoom makes it easier to judge distances
- Zoom makes enemy recognition better
Negatives
- Zoom gives you a view transition that can take you out of the immersion
- Zoom does force you to choose to use either a realistic size or a wide fov forcing you to switch between modes.
- Zoom in RO2 does force you to stop all movement if you want to have a realistic size.
- Zoom forces you to look around with your arms by moving your mouse instead of scanning the horizon with only your eyes.
- Zoom makes it that depending on what character class you have or what stance or state you are in how far you can see.
- If enemies use zoom you need to use it as well as otherwise they will always see you first and kill you first, if you as a player don't use zoom you end up at an disadvantage. (and remember you have zoom when you press shift, but you get zoom as well when you go to ironsights).
Now what you find more important is of course your opinion as where I have mine. Personally I primarily look at it from a gameplay perspective. Where the zoom in RO2 is very similar to the sniper scopes in games without zoom, together with the inability to zoom while moving makes the gameplay a bit similar to sniper only maps in other games.
Personally I never liked sniper only maps, and am a guy that liked to really push into the capzones and take objectives. Zoom makes it take much longer to scan the environment as only a small section of the environment is covered forcing you to use your arms to move around. And zoom can not be used when on the move which constrains your movement.
Defending should always be advantageous to the defenders, but I feel with zoom that it makes it more advantageous for the defenders than it should be which impacts my enjoyment. I much rather have fights between guys that have seen each others but have more issues killing each other, and getting more duels and firefights on. Than most of the time getting killed by someone I did not notice.
Now while I still hope for a classic version with no zoom. But as that is probably not going to happen what I hope for that I think is attainable would be the following.
- Make it possible to zoom anywhere at any time at my control. Indoors I do not want zoom not in ironsights. And outdoors looking at a building I do want zoom even when sprinting. Even though I absolutely love that there is less zoom in classic, the inability to control the zoom that is there still makes me dislike the zoom states of classic more over what realism shows.
- Allow people to always see things equally. Currently in classic while the zoom is somewhat reduced rifleman can see further than smg users. I think that the functionality of your eyes should not depend on what weapon you are using.
- Somewhat reduce the maximum zoom at least for classic. Currently MG's in classic have 2.3x zoom rifles 1.9x zoom smgs 1.7x zoom. It would be nice if at least for classic there would be a max zoom ceiling.
- Increase the general visibility in maps. I think some of the new custom maps have shown like Bridge or Red Assault and many others. That by having less fog and those kind of effects. That it actually becomes much easier to spot and take down enemies. And although of course you can see much further when zoomed the general engagement ranges often stay below 200m. Making the general experience for me much more fun.
So in short, my zoom wish list (if zoom stays):
- Ability to control zoom any time anywhere.
- Limiting the max zoom ceiling
- Same max zoom regardless of weapon or character state
- More general visibility in maps (less fog, blur etc like in red assault or bridges custom maps).
