Me and my sister duo Arah p2 and 3 any day, from first to last boss, without any exploit or trick. Saying the boss are like raid ones means you have no idea seriously ?They are embarrassingly easy, except lupicus. The only boss that I'd say to be bugged af is Grenth in p4, unless it's seriously meant that it resets whenever one starts attacking it with a skill that isn't autoattack.People don't do Arah because they simply don't do dungeons and it's overall better to run it without a full team because extra, clueless people only make it harder for the experienced ones, with aggroing stuff, ignoring mechanics, running non-meta builds. So yes, I'll rather duo and gift the last spots to friend and guildies, since making a team will likely mean pain.
