First off I'd like to say I'm loving the new update and the most recent patch to deal with the issue of useless defenses already dealt with one of my gripes. However there is another thing I would like to see dealt with and that is the current state of shards. I have been playing tons of C1 tier maps and have yet to find a single deadly strikes shard. I get that you don't want to make them too easy to acquire, but at the same time it's getting a bit irritating that I have gotten so many stun chance shards and not a single deadly strikes. So here is what I offer. Make the Gran-master a vendor that sells shards, but only sells shards of a certain tier if you have completed X number of maps in a certain difficulty tier. For instance if I finish 10 C1 trials I can find something like the power gambit shard. Once I finish 25 C1 trials I can find something like shielding guard shard. Once I get 50 C1 trial wins I can find the really useful ones like deadly strikes shard. As for the campaign shards it's the same concept, but finishing any map on any tier will add progress to it, but have it at a higher win requirement for them.
