Crowd control in this game is the worst it's ever been, to tell you the truth excessive crowd control of any player vs. player game is fundamentally flawed if a player is allowed to continuously damage a player while under the effect of a crowd control.
After many years of research, brainstorming and playing multiple games I have learned to cherry pick the best aspects of many games that involve player vs. player, to that end I feel in order to have a perfectly balanced and enjoyable player vs. player experience all stuns should be limited to no more than 2 seconds or the standard global cool down of that particular game, in this case World of Warcraft's standard global cool down is 1.5 seconds so because of this all stuns should be capped at 1.5 seconds and by doing so blizzard can remove the diminishing returns on stuns, the only form of crowd control that should be affected by diminishing returns and allowed to run the duration of 8 seconds in player vs. player are incapacitating effects or effects that break on damage.
The highlights to my proposed changes:
1. All stuns are to last no longer the 1.5 seconds but are no longer on diminishing returns.
2. All incapacitation effects such as (example) sap, fear, repentance, ect. will last its full duration of 8 seconds in player vs. player but share diminishing returns with each other.
3. All races, classes will be given a baseline standard skill equivalent to the player vs. player trinket on a 2 minute cool down.
4. All trinkets purchased for player vs. player will modify the race, class crowd control removal skill by adding effects such as lowering the cool down or adding an 8 second immunity to the race, class crowd control removal skill.
By adding the changes above we would add a whole new element of player skill, team coordination and individual player counter tactics leaving us with a player vs. player game worthy of e-sport.
If any of you guys/girls knows anyone in charge over at Blizzard please give them this idea, take the credit I don't care just get it done for the sake of all MMO's to follow.
