Game API allows in-engine data broadcast between addons of group members therefore enabling sync of ability ready state, cooldowns and buff information.
Game API allows ability button blocking and synergy prompt blocking.
Game API allows use of information extracted from visual 3D space for space orientation UI elements.

Result...
Robotic-level ball groups and also robotic-level single players are running around with:
- real time synced ulti state and blocked ulti buttons until expected set of ultimates is ready
- real time synced other buffs like expensive Rapid Maneuver and their button blocking to avoid resource dumping
- blocked Purify synergy prompt to avoid self-bombing with Plaguebreak or wasting it when it's not needed
- 3D circular overlay marking the direction towards the group leader on whom all group members throw all ultis and AoEs to ensure concentration and eliminate targeting errors in chaos
- automatic screen de-alpha or de-saturation when the distance from the leader is too large and the player is not in range of heals and buffs

API needs to be seriously limited in Cyrodiil.
Look at the code of some addons, it's insane. Broadcasting data between addons from player to player allows absurd possibilities for automatization.
While API doesn't allow button click and casts, the cast and prompt blocking is still absolutely enough for absurd automatization just in altered logic.
This superhuman robotic behavior is pushing both new and old players away from PvP or just make them switch to one single try-hard faction and disbalance whole campaign.




You people being frustrated from dying to bots, you do because DEV's allow it and for whatever mystical reason consider it in accordance with ToS.
