I wouldn't mind a buff to SWave druids, since I didn't see them get played this ladder, but generally they're a decent build like WarCry barb.
I couldn't find the change you were referring to, except in the Private Forum
Druid Thread where there's a couple sentences about SWave that never get detailed enough for discussion.
Since there's still time before the patch, I'll suggest a change and hopefully people can figure out what they want before this evening (I'm guessing that's the last chance for changes)
Proposed Changes1) Give Shock Wave at least the same Damage Tiers as WarCry (consider 25% higher because Barbs get 8frame cast rate with 100%FCR, while druids get 10frame)
2) Add a 25% Damage Synergy with Lycanthropy.
Justification of Changes1) War Cry is a very simlar skill, but does more damage because while it's base damage is about 40% less than SWave, it's extra synergy allows it to receive about 80% more enhancement than SWave, I'm guessing this along with a 25-33% faster cast rate is why people don't complain about WCry (also the BO synergy is a "Free" synergy as barbs generally max it anyways).
2) If the base damage of SWave is buffed, then it would be more OP in norm than it already is, so I figured it would be best to give it a "Free" synergy like WCry. Lycanthropy is the only skill I could think of to fit that Free-synergy idea, since I don't think Oak spirit is used by all SWave druids (mine never did anyways). Feel free to suggest a different synergy, even if it's Oak. The purpose of this synergy is just to slow down the damage progression. That can't easily be done with the damage tiers since players typically have about level 30-40 skills by the end of norm (so all the damage tiers are already used).
