In essence your trading one reward for another. This is just not worth the XP gain.
Our guild member finished the 100 kills, he levelled up 7 levels, he is a LLP started mid-lv.27 and is now lv.34.
Meanwhile he picked up many high stat rewards along the way, we expected he would level up much more, but the few levels was acceptable. It did cost him a few hundred gems to do this.
