I said collectively ...... hush! ;( /me runs off and cries
If you're ever given 15% crit for free as a Shade, you better have the initiative to push and improve your DD in other areas to take the most advantage of it. And it's hard to make nanos and items that incorporate any potential lag a player might experience.My point remains that calculations for YOUR shade have next to no relevance for any other shade. Not everyone spams perks as hard, not everyone has the same DD gear, not everyone has the same lag (takes longer to hit perks and slows DD slightly)... those stats are relevant for you, but noone else and this is true regardless of what professions' DD you want to discuss. That is why they are irrelevant to the larger picture.
Again, paper calculations != actual AO numbers.
Plus - correct me if I'm wrong, but I assume two Traders would both gain 15% and lose 15% from the other's buff, keeping their 30% crit intact and giving 4 other players 15% crit, making DD much improved for all involved
