Let me define these types of ball groups that we see in Cyrodil every day:
1. They are all Magicka players
2. They all use AOE skills for damage
3. They all slot the proximity detonation skill
4. They all slot resto staff and rely on that for healing each other
5. They all use the radiating regeneration skill
6. They run in towers and chokepoints then drop ultimates and harmony bombs
7. They usually all use heavy armor
These types of ball groups don't have any damage outside of their ultimates and harmony bombs because they all use extremely tanky sets and the only reason they can kill something is that they are using ultimates and harmony combined to do damage. These ball groups usually all use heavy armor and use many healers to stay alive and be extremely tanky while utilizing harmony trait to get very good burst damage that will kill you even if you are a very tanky player. There is no reason that these ball groups can do this much damage in heavy armor that not even light armor players can do this much burst damage.
The fact that almost all ball groups are all Magicka players can show that there is something wrong with how Magicka classes are performing in PvP. Fights with these ball groups are boring that always end up in the same results because of how unbalanced they are. They run in a chokepoint drops ultimates and harmony bomb and then you are dead that's it you can't even cast skills to heal yourself because how quick things happen let alone casting any skills that do damage so fights with these ball groups are very unbalanced and one-sided. It is extremely difficult to kill these types of ball groups so killing them first before they kill you doesn't work unless you run the exact setup they are using.
Things that can be done to improve things:
1. Adjusting healing so these ball groups can actually take damage
2. Adjusting harmony trait on jewelry so these ball groups should have to run other types of sets for damage and not rely entirely on harmony for their damage
3. Adjusting heavy armor so these ball groups can actually take damage
