Useless rolls

[Anza]

It's a bit strange to cater 2 rolls to one strategy which will end in less than a minute when doing so will take you 2 minutes to apply rolls, and 2 minutes to fix them afterwards.

You shouldn't need to fix them afterwards. Any fight you're basing on a SAM or SMN 2hr strategy should end in fast victory or equally fast defeat. As for your other comment, you also don't want any SAM stepping on each other's toes - if you have multiple SAMs, they should be taking turns 2hring regardless of what buffs the COR is putting on them. Part of the strategy is NOT interrupting the self-SCs, which add significant damage to the entire 2hr. This was common practice in Nyzul Isle back in 75cap days.

Don't need 2min to apply rolls either. Allies Roll on SAM, Random Deal, DD Roll #1 on everyone, wait 60 sec if you want and then DD Roll #2 on the non-SAM DDs. Besides, it's not at all hard to stand and get buffs correct at the start prior to engaging for something like a mission fight, pop NM, buffing at a Nyzul boss floor, etc. - waiting a short time to set proper buffs up shouldn't be that unusual.

Yes, my general tendancy would be to use DRK+WAR roll for someone specifically using meikyo shisui

Certainly a reasonable choice that gives some benefit. I'm not sure I agree that a chance of Double Attack proc that might not happen outweighs a guaranteed SC damage boost though.

And of course, if attack is capped (as may be the case in Abyssea), Chaos isn't doing anything for you.

I certainly think Allies is HIGHLY situational, and I completely understand if someone doesn't think it's worth the money. But there is a conceivable situation where it is the best option. That might never happen for you, and it's a pricey die, so I get skipping it. But it's not "useless".

Gallant's Roll is USELESS. There's NEVER a situation where you'd not be able to find two better rolls. Courser's is bordering on useless for the same reason - even if you did have a RNG-burn setup, something like Chaos/Tactician's will probably win regardless. Scholar's to me is useless other than some situations that will only come up in level 64-78.

It's ultimately a cost/benefit analysis on the situational ones though. Allies, Drachen... they're pretty darn situational (not useless though) AND they do cost a bit, so I see why people would skip them. Some of the other situational rolls (Magus, Monk's, Choral, Beast, Puppet) are also not too common, but the cheap cost of getting them weights in their favor.

If you do have a rng burn setup, most likely the rngs will have some sort of x-hit build set up, so tactician's is not helping. If they need ACC, hunter/chaos, if they don't courser/chaos.

Didn't Cerb, Khim, and Hydra all have massive magic defense? I thought the meikyo spam with wing was just powerful because SAM could unleash 7 WSs before the enemy got 1 off, and because sam was just stupid strong back then. Back when I used to do it with my static, our sam just used gekko 7 times- didn't even care about SC.
