Is there any plan to add information about combat specific add-ons, I know there is a pretty good UI thread already but it is a bit broad as it doesn't relate specifically to combat. For example I use slice commander because its compact and fits nicely beneath my characters feet and allows an at a glance look at my energy and time remaining on SnD, it’s a functional add-on but out of date. I switched mains for Cataclysm so I am still getting up to speed with competitive rogue play and have not found ideal add-ons to date. Nice thread, thank you for the information and hard work.

I think the real point is that neither of them is that good. Recuperate is such a small heal with for such a large damage loss that its only rarely worth using; however, Reinforced Leather defends only against a type of damage that we really shouldn't be taking very often anyway, so isn't particularly useful either. And most of the rest of the tree isn't much better - the strongest PvE talent in the tree is probably Improved Sprint, about which GC once said:

Which is a pretty good reflection on just how useless the tree's filler is across the board. You can make a perfectly reasonable argument for almost any talent in the tree purely by virtue of the fact that *none* of them give meaningful advantages.

yes, bandage too, I found renewed use for

They are definately both fillers. Sprint too is usefull mostly defensively. I didnt used to be worried abt running before WotLK. But then, for Sindragosa for example, I found that if I was 2 seconds too late, in starting to run before the AOE hit, I had no chance making it out of the AOEs sphere.
The speed boost available in the Assasination spec might be a decisive point for some. Quickening (which also gives a 20% all-healing bonus) is passive too and comined with Sprint can be "forgiving", in situations where a yard too late can hit for 50k damage. Combined with Nightstalker it yields stealthed movement near as fast as the standard speed of other classes.
Also a small perhaps rare situational benefit, Nightstalker adds to the value of Overkill as well, as often, at the end of a multiple adds or random ground damage (spots, vortexes) phase where everyone is sometimes spread out, you would otherwise forgo to stealth back on the boss, as the time wasted by the slower stealth movement, would decrease dps (by increasing time).

A more elegant way of making this macro is to do

/cast [@<name>] Tricks of the Trade

This will cast tricks without changing your target at all.
For example, my G button is my multipurpose button that has five different tricks targets.

#showtooltip
/cast [mod:ctrl,nomod:alt] Noggenfogger Elixir; [mod:ctrl,mod:alt,@Ebbon] [mod:shift,@Seeani] [mod:alt,@Radagust] [nomod,@Ashkev,exists,nodead] [nomod,@Arcen,exists,nodead] [] Tricks of the Trade

Each of the three modifiers sends the spell to Ebbon, Seeani, or Radagust, our three tanks. If the button is pressed without modifiers in a raid where either Ashkev or Arcen exist (two melee dps), it will first send the spell to Ashkev if he is alive, then to Arcen if he is not. If the button is pressed outside of a raid (a heroic, for example) where neither Ashkev nor Arcen exist, it will cast the spell normally, to allow clicking or pressing, in my case, G then F (to assist to the tank), or an F2-5 key for a specific player in the group. Needless to say the first line for Noggenfogger is just my choice, but you may use the ctrl modifier for whatever else you may please (another tricks target if you like).
