Actually it's not that bad. Min is 1.85, max 3.88. In overall sample size is too small to reliably derive TA though.

In all seriousness though, it depends on what you have, and if you don't have some serious offensive team like above I'd go with Slashley's recommendation. Soloing it with full heal-cleanse baka team (Attar/Demeter/Belobog/wild card) is possible using 'stun strategy', but it's goddamn long and boring as hell, so if you are not some hard masochist save yourserlf trouble and ask other people for help.
