I was actually just talking about this on wow forums and a little tidbit that isn't in the official patch notes but reported by a player, Simca, on his thread detailing undocumented changes:-Kick, Counterspell, Interrupting Gaze, Horn Attack, Backflip, and Interrupting Jolt now cause and are affected by the Resilient debuff.
No more 3 in a row interrupts from direhorns as well as no more spam charge!
On using Lightning currently, I'm playing one atm just for that pleasure beating the direhorn teams. Triple mech, while it sounds good, runs up against the slightly smarter direwhores who run 2 direhorns and an elemental or fiendish imp, I'm running tainted waveling(2,2,3), thundering serpent hatchling(2,1,1), sunreaver micro-sentry (2,1,1). This can lose now and then to direhorn/direhorn+rag teams if they get really lucky on the procs, but generally they get stomped, tainted waveling has an aquatic dot plus it's magic dot which adds to damage taken, in 3 rounds vs it's game over and they usually don't even realise until the end, when all 3 dots, all boosted by the magic debuff, tick on the same round.
