Glad you went and did the tests. Granted, playing ingame with mobs is different than a single target with gohm, but its easy to do. And, for the most part, holds up with scaling. You can do something similar with mobs: People like to use COTA (I think that's the one) in Festering - single elite, good mob, small area, readily reproducible. So, you can kill mobs in a real life controlled setting, record kill times, average a few runs, and make conclusions. You can also use video capture software.....start recording after windeup for about 15 seconds or so. Go back and note the life of enemies before and after...and calculate the multiplier. Alot more work, but more realistic.
But, yeah, the cast animation of meteor is what kills it. It works best if you alternate between WW and meteor. You just want to make sure you don't run out of WW's...cause then you're really screwed. MW/electrify, like you noted, shines when you have large mobs of enemies...and the lightning arcs to 3 nearby enemies over and over again. Its nuts for DPS. But with just a few enemies it basically falls off to the standard 10% DPS increase. Familiar/sparkflint has been brought up in the forums before, but hasn't gained much traction. I think you might feel the difference here between mobs vs. Gohm. Either way, its also a good DPS increase and, most importantly, doesn't use an attack turn. Electrify will shine versus mobs, and sparkflint will shine vs single target. But...since the game is played mostly against mobs, MW/electrify will win. You can also try Cannoneer....that was the one that Boozor I think used when he was playing around. Shards v Shell is a continual forum fight. Its between a 5 and 25% DPS increase and likely scales with your ping. Lower ping = more DS refreshes = more damage. Higher ping....not so much. So its usually the first thing to be swapped out (for shell) if you need more survivability.
Interesting with Ubers. I usually relax once King is gone. Cruise through until Mag is done. Then again, I'm always in groups....well geared groups. If I play aggressive and die trying to tank too many swarms and die....so be it. Someone will rez me. But Litany ring def helps. And running UA instead of CB will help.
BTW, did you actually calculate the eDPS or damage multipliers? Or just note the kill times. It'd be interesting to know what the multipliers were for each test if you don't mind doing the math, lol.
