You can do the sites just fine in a HAC. Not that there’s any point. No suspect timers or anything when a destroyer just warps to the reward site and steals your loot, your choices are:
Do the site and loose the loot
Do the site, red sec, kill the thief, get concorded
Ignore the event.
Honestly at this rate CCP just punish anyone that actually interacts with their events. The events are for griefers, not for players.
I’m going to ignore the event. Probably going to let my Omega expire for a while too.
