Regarding your arena questions...




When enter any Supression field less the 75% ie: 25% or 0% You are given a 15 second decide what the hell you are gonna do time limit which means your open for attack in 15seconds so you better decide to stay in the zone..or get out. This goes for the arena as well. When entering inthe arena you'll get a notice on your screen saying "Mayhem Zone this is Total Chaos" blah blah ..you now have 15 seconds to step back outta that zone before Anyone in the arena can target and attack you. However not anyone can...Depending on your level..if your below 75 ie: 74 and less no one above 75 to 200 can attack you unless you attack them first. Beware of gankers....(mostly agents gank) but beware of them before entering...if you see no one in the arena and tons of people outside..it could be that there's an agent invisible in there waiting for someone to step across so he can killem =/



Hopefully that helps
