I remember when I suggested 50 clade xp for parcels! and people were like I dunno that's too much! And it's like nah.... that's just right. I would take the trophies exchanging for clade exp in town. As much as I love pulling up and getting my 2g off tusks or whatever, I'd take 100~ clade exp! That stuff adds up. Like I said clade should be something you constantly are gaining by playing. It should take awhile to get to 20 but you should be getting there without 'trying' if you are really playing.
