This is an image of my buff tracker while standing in a typical "ball group", or coordinated 12 man PVP group, on PC NA. I do not have echoing vigor or radiating regen slotted, so those 11 casts of echoing and two casts of radiating regen are being generated solely by the 12 man group. This is in addition to the 2-3 casts of healing springs/ritual, and the 2 casts of healing combustion present. There are also sets present that will proc healing (earthgore), and other secondary effects such as passive warden off heals, lifesteal, etc. The players in this group are receiving at minimum 10 ticks of healing per second while engaged in combat (or while simply sitting on a ram, spamming their heals endlessly).
The recent change to snake in the stars that brought it's proc cooldown while active from 1 second to 100ms is a great change towards combating these groups and the heal stacking problem. However, the set can only proc on one single person every 12 seconds. Applying a 10-11k oblivion damage dot to one single person in a group like this does nothing - these groups already have so much healing that they're able to shrug off things like coldfire and oil.
Meanwhile, even though the recent changes made the set less potent against your average "solo" or "ungrouped" players, it still will be very oppresive against them if they're using multiple heal over times, which the vast majority of players do.
If the intention of this set is to counter the heal stacking issue, as mentioned in the recent developer comments, then you need to remove the 12s cooldown on application for the caster. The other two cooldowns will still remain; a person can only have one instance of star venom on them at a time, and they may only be affected by star venom once every 12 seconds. Allow for the set to be applied simultaneously to multiple people, so that it can be applied to the entirety of these ball groups at once, negating some of their absurdly high healing and making them temporarily susceptible to burst.
If you do not make this change, this set serves no purpose other than a frustrating tool to be used against solo and outnumbered players by superior numbers. It does not disrupt ball group play at all, and we will see no improvement to this incredibly unhealthy and imbalanced playstyle which is also completely decimating the server performance for PC NA.
