There's a difference between making something that's too hard a little easier, and absolute entitlement easy mode. Yeah, it may be a hassle to move a few cells north from the Culvert entrance NPC to the Kafra NPC, getting a pront warp pass, using it, walking to the recruiter and receiving some free stuff, and getting teleported to the Culvert entrance NPC again. But honestly, that's the easiest entrance quest in the game. And besides, instead of doing that, I always kill thief bugs on the field. The spawn rate could be better, which results in having to walking around a bit, but you'd be walking more in the culvert trying to find them due to having to walk across all those bridges and such. The spawns aren't any better in the Culvert, and they're all most likely spawning on the far side of the map due to people killing them near the entrance.
Also, especially for level 10 characters, the familiars can hit hard. No familiars on the field map...
