Easier counterspelling might be actually the best option to "nerf" spellcasters without really nerfing them.
Imagine counterspelling was always an immediate action, and Dispel Magic gave you more flexibility. (Maybe it shouldn't be just as easy as expending the slot, maybe you'd want a caster level roll.) The spellcaster has still all the firepower he used to have, but it can be countered more easily, and he will want to use it for that purpose, too...
This is what I was referring to above, re: using a Reaction to counter a spell.
I believe an appropriate counterspell would be
a) the same spell (haste vs. haste)
b) the counter spell listed in the spell description (haste vs. slow)
c) dispel magic counters anything
However, having said that, I think the possibility that a caster can lose his action AND his spell is probably too steep. Counterspelling sounds all well and good when it is the PC doing the counterspelling, but it sucks on toast when it's the bad guys doing it to you.
I'm not sold on my own idea.
