The one thing I can see as being an issue is yes, long fights will be a pain in the ass. Short fights like say festergut or saurfang 3 shards may be fine, but say LK normal or hard lasts for 2-3 times longer than those 2 other fights and your stuck with only 3 shards with no way of regenning them in combat. As has been said no other class has got an ability that is limited in uses per encounter. Sure some have long CD's but if the fight goes on for longer than the CD, hey look...it's up again!
For a lock however, if they burn their 3 shards in the first 5 minutes, say during blood lust popped early to force a faster phase 1 or whatever of an encounter, they are now totally out of bust cards to pull. A pally can pop their wings again, a shaman can pop lust a second tiem if the fight is long enough, can pop their fire elemental again etc. All the burst moves can come back for many uses in a fight but witht his a lock is boned if they use all the shards earlier. One solution I can see if just getting killed, brez and have 3 back again, but that would hardly be optimal.
