I agree on the enmity thing...

I think a good solution would be to change the enmity gained from ranged attacks to strictly (or almost strictly) volatile enmity (the kind that goes down with time), removing any link (or almost all of any link) it has to cumulative enmity (the kind that goes down when you take damage. This would give rangers a little more control and the option to "hold back" for a while til the mob forgets about them (with CE, the mob doesn't forget).

Rangers DO have one advantage over MNKs and WARs as well... the ability to deal damage while avoiding AoE, -ga/-ja spells, auras, etc... (unless they're the target of course). Being able to stand at a distance and do good damage is a pretty nice advantage.

I like rangers... I kinda think they should work as somewhat "stealth" damage dealers... snipers or something... It's definitely a niche job - I'd like to see it get more opportunities...

One thing I'll say about the job as an outsider... I don't really view RNG as a "main job" people play full time. I'm sure some do... but I've always viewed it more as a "special" job used for certain fights where more conventional DDs aren't as practical. (Not many of those exist right now, however... to me RNG feels kinda like BRD or COR in Abyssea... nice to have... but a luxury of sorts... and you probably won't find one around).
