Overall, I do fates and dungeons. 1-12: Horizon in Western Thanalan (Thanalan) 13-20: Aleport in Western La Noscea (La Noscea) 21-30: Quarrymill in South Shroud (Black Shroud) 28-34: Wineport / Costa Del Sol in Eastern La Noscea (La Noscea) 30-41: Dragonhead in Coerthas Central Highlands (Coerthas) 42-50: Ceruleum Processing Plant in Northern Thanalan (Thanalan) Personally, im not into fate botting with Reborn. I mainly use Orderbot and CombatAssist. My experience and problems with FateBot are: every bot follows the same route it attacks random mobs and at 40-50 it runs away from Dark Devices - so every kinda assumes your a bot, reports inc. It works as a fatebot but it has alot of flaws. Thats my own experience.
1-14 Smmerford Farms 15-19 aleport 20-24 Quarrymill or camp drybone 25-34 Costa Del Sol. can move to Camp Bronze Lake when you 30 35-44 Camp Dragonhead 45-60 Ceruleum Processing Plant
You can mitigate these two problems by blacklisting troublesome fates like DD and Eyes (as a melee), and setting the bot to return to specified point, and set the point away from the aetheryte and large clumps of people/botters.
setting the bot to return to a specified point is a great solution to not associating yourself with the other bots. Blacklisting the highest XP output in the area i feel isn't, unless you can play those fates by hand. My personal feeling is RebornBuddy isn't for afk leveling via fatebot at the moment, atleast without somewhat more support. Certain fates need change in positioning (etc. Eye), in the case of DD, the bot simply needs to stay throughout the fate chain and there should be an option to ignore mobs that aren't apart of fates. You can still use fatebot, and it works, although its slow. Personal experience, it took me approximately 3-4 hours to go from 31-32 on DK due to the bot trying to fight mobs on the way to fates. (would run away when low, heal, walk towards the fate, aggro random mob and fight through the duration of the fate.
Because I wasn't super efficient and had time to kill, I did Summerford Farm from 1-35, and then 36-60 at Dragonhead.
I do 1-10 grind regular mobs 10-20ish aleport 20-30 hawthorne 30-40 costa del sol 40-50 Coerthas Reason for this is you get a fucking 100% bonus xp and so yeah tons of fate here. I avoid north than at all cost because its congested with botters and bot reporters.
