Useless rolls

[Yinnyth]

BST, PUP, DRG rolls you will most likely never use unless you have friends who really enjoy playing pet jobs. PLD roll is the laughing stock of every roll and has no situation in which it's useful. BRD roll --could-- be useful, but mages always prefer the other rolls anyways. NIN roll you could probably go a year without using, but if you play the game long enough, you're going to find yourself in a situation where the evasion might be exactly what someone wants. DNC roll is fairly weak, and most corsairs never use it... I pop it out when there's nothing going on for a while, but you could probably get away without having that one. BLU roll I've only ever seen used on AV way back in the day when we were still trying for a legit kill on him. MNK roll used to be useful, and still could be under the right circumstances, but no DD will ever ask for it by name because their pride won't allow them to, so you can probably skip that one too.

As far as the new rolls go, allies roll sucks, badly. It only boosts SC damage, and even if you roll XI on it with the AF3+2 gloves to enhance it, it's barely noticable, so you can definately get away skipping that one. Blitzers roll is worthless imo since it's weaker than most other forms of haste and it slows your TP gain to match the delay it cuts. Courser's roll will be useful if they ever do HNMs where a firing squad of RNGs lines up to kill it from a safe distance, but currently it's mostly without use. Though you might use it on yourself at the higher levels to help skillup your marksmanship. I think that's about all of them...

haste samba does the same thgingand people still use if and since it not haste it - delay it stacks with haste, haste samba, and marches

Samba counts as job ability haste. I believe hasso and Apocalypse's aftermath also fall into that same category. Blitzer's roll lowers the TP you gain per swing, haste samba does not. Also, 'borrow' is spelled with two 'o's.

Blitzer's may lower your TP per swing but it doesn't lower your rate of TP gain. Since the TP formulation favors lower delay weapons, it will actually help TP gain slightly (much like DW). It will throw off XHit builds (just like regain will) but seriously who fusses about X Hits anymore?
For 1H who haven't reached delay cap and are getting high crit%, Blitzers would be a very good roll. Certainly I use it soloing on COR since I only have gear and Samba Haste in that setting.
AS far as useless rolls are concerned: Gallants, Allies, Coursers, BRD are the most useless. Pet rolls are highly situational. NIN, MNK, Magus all can have uses and I wouldn't skimp on them. I'm finding WHM and SCH rolls to be my least used mage rolls as I prefer Fast Cast/Evokers/MAB to be more useful. MACC roll is situational (i.e. you brought along some gimped mages lol).
