Word of Warcraft did it right, why did bioware not take this idea from blizzard like they stole almost everything else.. This one actually works well.
Copy World of Warcraft:
Remove Acid
Remove Rounds
Put in Dampening: http://wow.gamepedia.com/Dampening
Add Vision crystals to see stealthers in stealth so they cannot troll
Results:
Sorcs can't win in acid from barrier because there is no acid.
Faster games
Faster queue pops
Other healers may be viable along with sorcerers (who am I kidding mercs will never be viable.. just operative)
Dampening Definition for people who don't want to click the link or have never played World of Warcraft:
Dampening begins after 5 minutes after a 4v4 match begins. After dampening starts each player will gain a stack of the debuff every 10 seconds, reducing healing received and damage absorption effects by 1% per stack.
