A build that can only take on one monster at a time is next to useless in my eyes. Any build should be able to do that. However it's nice to see ideas for different things.
Oh, by the way the major runes only cause -35 health now so if you have an older rune swap it for a new one to get back the 15 extra health
I did that with my warrior with 2 major runes and got back 30 health.
