Wow....What the hell? I guess I'm a noob now!

What is the prot rate of a lightning strike? If a lightning strike averages 600pts of dmg, by your 10/swing that has it going off every 60 attacks.

I haven't seen recordings of extensive testing nor have I been bothered to perform them myself so that's based on what I've read and heard, 10 would be counting quite low.

Of course you also have the rogue auto SA dmg once the radience goes off.

Yes, and as I previously stated it is quite possible to get ~100% SA even without radianceII weapons, which should be obvious to any vet.

Plus a Lightnig II strike could go off on a trash killing it, and not all the damage being counted. Where the rogue SA thru radeince is more constant.

Yes, and hypothetically it could go off on the first, second and third strike against every mob in an entire quest, thus providing +~600damage/attack, however unlikely that would be.

So examining the validity of your hypothetical situation:
Lightningstrike will on average overkill so much that the lightning strike will contribute as little as to be equivalent to radiance, making the erroneous assumptions that radiance will never result in overkill and that lightning gives 10damage/attack, in order to favor your hypothesis.

Now 2.8/10=28%, i.e. on average 72% of the damage of the rad will be overkill.
This would imply that half the hp of the mob is equivalent to 28% of lightning strike damage of 600, i.e. mob hp of approx 336.

First off the mob would die just by looking at it, secondly you would kill it before loosing SA if someone else just grabbed first sight aggro, thirdly the probability of radII to not proc would be 64% and finally you wouldn't bother to melee since the mob would die so easily that ranged would be more viable than melee.

I like generalized statements saying 1 weapons is better then others. It allows the reader to cut thru all the actual facts of the weapons based on a particular class and simply just follow the more inaccurate conclusions. Of couse they don't have to read pages upon pages of caculator garble, and can simply just pick by assumption, it is quicker i suppose. So here's my general all BS no fact statement, since those must be what works for proper answers:

On a rogue, Radience II > Min II or Lightning II

Yeah, but why?
I totally get the convenience of being able to zerg off on your own or soloing, once again that's probably not sound advice for a new player though.

And why is convenience more important than being able to contribute as much as you can where lack of contribution is likely to lead to failure?

Most failed shrouds I've been in have been due to a combination of lack of DPS and healers unable to keep people up for the extended time to kill resulting thereof.
