For example: You have 50% resilience rating and get hit by an 8-second fear. That would mean that the duration of fear is cut in half, resulting in 4 seconds of fear.
Some would say that this way CC would be almost useless, since resilience will reach over 70% in the future. Then I can propose that pvp power also increases the time of CC by the same amount, until the cap of 8 seconds.
This way a if a player with 60% resilience gets feared by a player with 35% pvp power, he will receive a 60-35= 25% reduced fear, that is 6 seconds.
A decent idea, worth the thought. If however they properly thought CC through (listened and stopped adding more instant CC that's unlossable into the game) and made it a more skill orientated part of this game, then this wouldn't be required.
The equation is damage VS the need to control someone. For example you CC the enemy healer in order to do damage to you're kill target without it being able to receive healing, ergo stopping 1 of the enemy team being able to contribute to the fight for a period of time.Individual CC needs to be re-thought, blanket changes are the problem with this game
. If more thought went into game balance, people wouldn't feel the need to propose such huge blanket things, like you are right now. What happens with teams that need the current length of CC to get a kill? You'll end up with games that last until the arena finishes. What we want is to move away from people being able to kill people in seconds and instead games where mistakes punish bad play but A) Not in a way that causes you to lose straight a way and B) Not in a way that causes mistakes to not severely effect the out come of the game. Something we call "Balance"
Also who would benefit the most from this change? Just off the top of my head Restoration druids would gain massively from shorter duration CC. Sometimes I try to time my CC so that that a target has 1-3 seconds left on lifebloom so the druid is CC'd when the stack drops off. Your change would especially be an issue against teams without an offensive dispel. Well timed CC is needed so that the druid is unable to re-apply the stacks, trying to kill a fully hotted target is pretty tough. This change would be a huge buff for hot based classes. Although a reasonable idea, you haven't fully thought about it's implications with regard to everything, but then again you seem to be in the same boat as the entire blizzard class balancing / PVP team (Not a direct snipe at you, you're idea is well reasoned but flawed, this forum needs dialogue and conversation in order to contribute to game balance, well that's the idea, it's not happening though!).
