I also only slowly progress through the tournament rounds (currently 77) as I typically select targets with low allies in order to minimize unit losses and EXP gain (and it seems there are abundant low defense/low ally manors/silos/etc as well as the occasional fellow making a breeding den run).
To be honest the main thing that levels me these days is the Boss events themselves, as each boss gives quite a bit of EXP. I typically level 1-2 levels per event. I have gotten to the level 15, and 30 boss without gems for the last 3 boss events.
