This is mostly from a BG perspective.

Endless Fury - We are trying to change all these things about mag sorcs to balance them. At the end of the day, the only real problem with Sorcs is Endless Fury. Sorcs don't top scoreboards in BGs for any reason except for that they have an auto execute. Just change the skill so it doesn't just sit on the person until they drop below 20% health. You should have to time it. Or make it so it only executes if you did most of the damage to the target. Sorcs are already at an advantage because they can execute from a distance. Just make it take some skill. I know sorcs that say, I don't BG because I don't do anything except execute. You do all the work and I just sit back and steal kills. If you want, give them a buff to offset this nerf (if you really call it a nerf, I'd just say it's more of a fix). I don't care, but just fix this skill.

Healing/Grouping - This game promotes grouping up way too much. I understand that we want to encourage more casual players to PvP which means allowing them to have more success in PvP. This is largely accomplished by allowing casual players to outnumber their opponents, implementing an AoE cap and promoting staying close to allies for group heals/buffs. But it's gone too far. Healing as a ball group is just too strong, even in in BG. At very high level play with organized groups, this game is mostly about timing ults together and stacking up for heals. Games often become boring where teams have extreme difficulty killing each other. We need to spread the fight out a little. I'm open to ideas on how to best accomplish that. At the end of the day, when 4 players all sit on each other, they need to be punished. It shouldn't be good to sit on each other. Stay close, don't get caught out, use your teammates, yes.. all these things are good. But group up, pop aoe buffs and heals and just sit there, that shouldn't be a thing. That should be punished. Out in Cyrodill, fine. I get it, you want to protect the casual players. And don't want 4 players to come wipe them all, so I get the AoE cap. But don't ruin BGs. You already have an MMR system to protect players. That's enough. Make them have to land abilities. Make the good players have to do more than hit 2 dawnbreakers at once.

How to accomplish spreading people out? A few ideas. Nerf group healing. Improve AoEs. Implement a healing cap (e.g. can only take so much healing over a given period of time - this will help with the overly heavy support teams where no one can kill anyone).

A few other shout outs. Speed pots are OP (yes I know everyone can use them, but the duration is just stupid). Purge needs to be fixed. A DK can apply 3 dots that all get removed with one button that is spammed. Put an increased cost for use like dodge roll or something. But its just too strong against classes that have no option but to play dots.
