You know, I see a lot of people AGAINST the idea of keeping your skills in level synched content because of their concern for the newer players. A lot of people are blasting veterans saying they just want to "Steamroll over new players" and how "unfair" it would be. Well, in my opinion, it's not about that.
1) Right now, some of us don't run low-level content because it's boring and we can't do it with friends without directly que'ing into the instance. So right now, I'm not doing low level roulette because the tomes are a joke and the content is jsut SO BORING because of the lack of buttons to press. Sorry, but 3 button gameplay is NOT fun to me.
2) Having access to our full kits, you're worried that we'll rip threat off the tank and then blast them for being bad. Here's the thing, though... We already rip hate off the tanks. I have no problem on DRG or BLM if I ST and the tank is newer ripping threat off the tank. It's very easy to do pre-30/40 with newer tanks. This is a responsibility of the DPS to not let this happen.
3) Having access to our full kits, you're neglecting we get ways to manage our threat. Dragoons recieve elusive jump. Black Mage and Summoner cross-class Quelling Strikes. Monk has naturally low potency strikes to avoid generating large threat and relies on pumping out damage fast to make up for it. Not having access to these skills actually reduces our abilities to reduce threat. Having access to all our CD's also hurts because we can't negate damage as much - stressing the healer more.
4) What about tanks that want to do low level? Imagine a paladin with Shield / Sword oath in level 15 dungouns. Their threat will be rediculous. DPS could really go all-out if they wanted to.
5) Faster runs dont' necessarily have to be a bad thing. I don't get why people think that it's only speed runners that want faster runs. Faster run = more mobs killed per hour for low-level players = faster leveling experience.
These are just some of my opinions on the matter. There will always exist counters to each - such as people just being ****y human beings in the first place. But I'm going to be honest with you... People will be ****y human beings regardless if they get skills or not. Those people are already being horrid people.
