Change in Elem. Shaman timers in 3.2 ??

[HelmoAlkou]

Was there a timer change in 3.2 with Shaman dps spells? I use a /castrandom macro, which I'll post, that is all of a sudden leaving my Shaman standing around and waiting between cast. And I mean waiting for 4-6 seconds between some. I've gone over the patch notes several times and the spell description in game without any ideas as to what's going on. I'm also trying to drop a spell out of the lineup macro, one by one, and nothing seems to prevent this standing around. And I don't think it's just me, dps and down greatly and it's taking forever to drop a boss.
Please let me know if you've seen or heard of any changes.
