The rank 15 leves that require a rank 20 synth as a quest item, has given me guild marks. And those synths are easier to do than a synth at your current rank level. IN order to get the guild marks you must succeed at ALL the attempts. (For 100% Guild marks as a reward). Less than 100% success on all attempts reduces your chances of getting guild marks.
Anyone notice the rank 1 leves are harder the higher your rank above the synth is? Seems there are no free rides for crystals and shards.
