Well, I find that meriting Phantom Roll to a lesser cast time in the Tier1 merits kind of redundant. The rolls last 5 minutes each, and you can only really roll 4. 5 is too much. So getting out 4 rolls in 5 minutes with the 1 minute recast isn't a problem at all, if you are on top of your shit.
So when I do eventually merit Corsair, I will be pumping Merits into Quick Draw Accuracy and Quick Draw Recast. Accuracy is for Sleep and Dispel mostly, but those extra pwn shots against HNMs would be kinda nice. Wonder if 5 Merits in Accuracy and the Tricorne would get you to sleep Cerberus or something...
As for the Tier2 Merits, yeah, they are totally awesome names
Snake Eyes I will put 3 Merits into to get the recast as low as possible, and it better be a 5 minute JA with Additional Merits lowering the cast time by 30 seconds. Winning Streak might be worth it, because that will allow you to roll less often, so you could concentrate on funner things like Meleeing and Shooting and whatnot. Fold would be interesting, but only dependant on how often you bust, really. Personally, if I roll something and don't get the numbers I want, or miss the people that need the buffs, I will purposely Bust the roll (Run away and Bust it on myself so the others don't get the negative effect). That way, in 30 seconds when Phantom Roll is active again, you can run up to them and try again. This in turn allows you to roll any roll you like consecutively, (Say you went Bust > War Roll > Smn Roll, you could go War Roll again if you missed someone or for a better number because Bust will still be in effect). So Fold might be worth looking into. Loaded Deck... Kinda useless... If they made it so that it has the opportunity to reset up to 3 random Timers (Magic, JAs, whatever), then that would be awesome.
So:
Tier 1 = Quick Draw Accuracy x5, Quick Draw Recast x5
Tier 2 = Snake Eye x3, not sure on the last 3... Perhaps Winning Streak x2 and Fold x1.
