I agree that the range and cooldown should be nerfed, maybe like 30-40 seconds and 5 yard range. But honestly some people are too stupid to play their classes
You guys need to learn when to use your stuns, and use the correct skills at the right times. For instance, I lost to a druid because he rooted, ran and healed when I used counter. When root ran out he would use either tornado or the new skill, so I was stunned most of the fight and counter was completely useless. A smart warlock I fought used the statue skill when I activated counter. It's all about timing and changing your order of skill usage when going against different enemies.
