Second. Make Cc's be casted again and give them cooldowns similar to hex.
Third. Take away class breaks to cc or make them a higher cooldown such as 2 mins.
Fourth. Make all classes have an equal amount of life saving abiliites for themselves when their partner is cc'd.
Fifth. Rework stats/abilities to make burst damage through use of CDS not deal as much damage.
Sixth. Make all healers except cast spells again. Remove all "anti interrupt" mechanics. Make then rely on partners, positioning, their 1 instant cast oh $*@& heal every 1-3 minutes"
Seven. Remove the use of spellsteal in arena or atleast give it a cooldown.
Eight. Make casters use mana again all of them make healing constantly without drinking run you out of mana regardless of gear. Make dps casters rely on casted spells for damage. Stop giving instant cast abilities chances to proc other super high damage spells. Bring replenishment back for raiding to help counter this.
Nine. Fix the gear difference between dreadful and malevolent pieces. The desparity between the two now that you have allowed 6+ weeks of mmr inflated cheating teams to get 1000's more cq points then they could have ever gotten you are seeing fully geared with elite weapon players in lower ranks. I would add the malevolent weapons to the honor vendor for this season only to counter this.
Please work on PVP more than you are. It is stupid that the second an issue with PVE comes up you drop everything and fix it right now youll shut down a server to fix a coin issue with raid loot. However you'll allow exploiting and silly imbalances to destroy an entire arena season before even taking a glance.
We keep hearing from you "We think X if fine" etc etc. Well learn that you can be wrong. Swallow your pride and fix the game for your customers.
