TORWars:
You recently revealed the group stealth system for Smugglers and Agents. This sounds intriguing and fun. Can you expand on the details for us? What kind of range limitations are involved? Is there a cooldown or can it be used repeatedly? Can one Smuggler enable stealth for an entire 16-player Operations party?
Zoeller:
Scoundrels and Operatives get, at higher level, the ability to temporarily overload their personal stealth field generator to cover an area of X meters around them, effectively cloaking every member of their 4-player group, but not an entire Operation party.
In testing currently, the stealth field stays active for a duration of 15 seconds and cannot be reactivated for 3 minutes after use due to the load it generates on the generator. Players who really like this skill can specialize via one of the skill trees to decrease the cooldown to two minutes.
While we initially had the group stealth field available to Gunslingers and Snipers, balance considerations from testing have lead us to replace it with something more fitting: these Advanced Classes instead gain the option to create a large defensive screen (similar to cover) around their position while in cover, protecting allies from incoming damage. While the stealth field is great for sneaking up onto objectives, the defense screen is great for holding onto them.
Mola!
