Chain stun.
I feel like chaining stun is out of control and not fun. When you get stunned and 2 other enemies have stun, either it be skill shot or click-to-stun, the stun times are lasting ridiculously long. Now, when there is a click-to-stun player with 3 other stunners, the stun chain lasts until you are dead with 0 reaction time. Click-to-stun, in general should not be if it is as simple as clicking a button on them to stun. I feel if there is a stun in the game, it needs to be skill shot and the chains should not last as long. If you are stunned for 2 seconds and stunned again immediately, it shouldn't add more time to the current stun timer. After being stunned once, the stun should then have diminishing returns within a given amount of time such as 5 seconds. The way cc can be chained in general currently, is not fun and makes tenacity feel almost worthless.
