[/QUOTE]We started playing 5e about a year ago and have had two campaigns. I'm two for two on multiple members with the spell. As for your assumption that 6 wizards don't have the spell among them, well, it's far more likely that all 6 will have it than none of them.
So in your experience which isn't a general experience. It has nothing to do with my assumptions. You can just as easily as I look at how common casters that have the possibility of casting counterspell is compared to the number of classes that cannot in general play. It would be rare at most tables to have more than 1 character than can cast counterspell.
So you have a solution(s) looking for a problem that doesn't exist for the majority of people playing the game. Additionally, this is easily solved by the DM through intelligent encounter design. You claim that you run casters intelligently, then do so. Every caster in the world should know they have the potential to be countered.
Frankly, you should stop playing D&D for a while and try a game like Shadowrun in which problems like this have to be considered by players all of the time.
If you as the DM are worried about player negation, well there is a simple fix for that: Don't give all your casters counterspell. Pretty simple.
Also from your description this is also only a you problem as it is your house rules that allowed partial identification of a spell during the reaction.
Counterspell has a cost in the game. Unless you have some other house rule in effect, Wizards and Sorcerers have at most 3 3rd level spell slots. If your party isn't using those slots for other more important spells you aren't running them through enough challenging encounters to drain their resources. If every encounter starts with all casters having full spell slots and everyone can unleash a torrent of counters, that is a problem with encounter design.
So before bemoaning that counterspell is too powerful, you should really check your design assumptions and make sure that you issues with the spell are a general issue and not a specific issue. As none of the games I have played in, nor any of the games I have watched have ever had this "issue".
If you want to nerf counterspell for your games, that's great. But don't believe this issue exists beyond them.
