Even after all this time, this is the job I love the most. My initial response, while taking it from 1 to 75, to everyone saying "/NIN?" all the time was "I'm fine without it, thanks." The challenge was to take it from 1 to 75 on /WAR alone and I did, but I eventually stopped being stubborn (semi-lazy I guess) and leveled up /NIN which I now use more than /WAR, but if I have a good Bard for when I pull hate, I'll bring /WAR back out from time to time. Now, at level 90, the job is as good as it's ever been in team combat, but the main idea of a thief is that we are able to get what we want using our skills. So I would like to post my suggestions based on my experience with this job after all these years of doing it.
First off, Thief's Tools are something I rarely have used. My success rate with them has been less than impressive to me, and I enjoy killing things, so I've worked to farm keys when I need them. It would be nice to see a system introduced along the lines of say, fishing or Abyssea pyxides, where we can actually open them through skill using tools, skeleton keys, or living keys. Each key would require different things from us. I haven't completely thought this through about what could be done, but having 3 types of keys that we just use like a regular item and hope for the best hasn't impressed me much.
Second, Treasure Hunter against some monsters (like Aht Uhrgan Beastmen) seems like a waste. Why is it that none of those Beastmen have scrolls like the Beastmen of Mindartia and Quon? I know it's minor, but it was always something that bugged me a little bit so I thought I'd get it out there.
Third, Mug... why 15 minutes? I assume the original thought was "we don't want people just mugging 1 thing after another and getting gil that way and exploiting it", but seriously, few things can be mugged more than once, and aside from Notorious Monsters (which all respawn more than 15 minutes later), you can't mug a significant amount from a monster assuming it even drops gil (which are the only things that can be mugged). Heck, even if you dropped it to a 5 minute recast, I mug anywhere from 1 to 100 gil for the most part even with my Assassin's Bonnet equipped, so, at best, I could make 2,000 gil in 1 hour from this trait just from normal monsters. Nothing all that game breaking as far as the economy goes wouldn't you say? Or, if you want to keep it at 15, could we get a job trait that would cause it to do damage of some kind? We have Assassin job trait that affects our Trick Attack ability, so I know that can be done at least.
Fourth, why are Steal and Despoil on the same timer? I have Aura Steal merited just in case stealing an item fails. However, if Despoiling an item fails, I lose Aura Steal anyway and I've done nothing. Then I must wait 5 minutes to try again for any of them. I'm a thief so why couldn't I attempt both? It just seems debilitating to the main idea of the job to not allow us multiple ways to take something if the first way fails. Also, why is it only on very rare occasions that Notorious Monsters have items to steal (using Steal to get the weapon needed to kill Brigandish Blade was a brilliant idea, for example) and it seems that no Notorious Monster has anything to despoil? Perhaps it's a temporary oversight... or at least, I hope it was.
Finally, my ideas for job traits/abilities. Again, I don't think they're game breaking and it would help to add to the uniqueness of this job:
(JA) Vigilance - Temporarily increases evasion and parry rates. Duration: 30 seconds Recast: 5 minutes
(JA) Con - Not sure of a good in game description for it, but it would be similar to Hide in that it drops all enmity, but this would be used on things normally not fooled by Hide. In the case of Con, however, we would need to be face to face with the "mark" as it were. So it would be ineffective in a "run away" scenario. I would see this as being useful when say, using Accomplice on a WHM that just used Benediction and you just got the monster's attention. Duration: Instant Recast: 5 minutes
(JT) Gilgame Heart - Occasionally converts a percentage of damage taken to gil. Activation rate: 3% Damage to gil: 10%This might be able to be abused, so activation rate and damage to gil conversion might need adjusted, but again, the whole idea of a Thief is that we know how to acquire things of value.
