Pretty obvious what this thread will contain. Basically, there are a lot of items in AO that have level locks for good reason... And there are a whole whack of quests/items that have level locks that simply don't fit with the valuation /progression of newer items.
Many people think level limitations are bad game design, and I think there are several fairly obvious ones that could be removed.
First up: Quests that really need the level lock removed.
1. The most glaringly obvious: Sergeant Marion Sweet Level req: 120+
Why? The reward is usable from level 100+
2. Corporal Ashley Winstead: Level req 120+
Slightly less obvious, but there's really no reason why this level lock is in place. If you can complete the content, and twink into using this nano, by all means you should be able to use it. Most nanos are of comparable power with higher level RK nanos or scheol-to-pen quest level nanos which are finished by toons (I've seen) as low as 60. The level 120 req is a bit absurd. I'd prefer to see the level requirement removed completely.
3. Inferno tours: level req 175 or 190 (I think AOU says 190 but iirc it's 175)
Since the addition of the Viral belt component platform which is significantly better than the <base stat> component platform which is the reward for this quest, there's almost no reason to do this quest anymore. I think it's fair to say that if someone really wants to go all out to get 5 more of one stat on the belt... might as well let them.
Items that could use a level lock adjustment:
1. Alien beacon/reflex/battery - level 126... These things are not exactly uber-powerful by any means I'd say just get rid of the req entirely.
2. Alien Augmentation huds - If anything, lock them to a level 100 limit since you can go to S10 at level 100. It's kinda ridiculous that you could work hard building a TL4 twink but not be able to use the loot you gain, right?
3. Maybe I'm out of line on this one, but I kinda feel like Dreadloch items could use a level lock adjustment
I'm sure there are more, but these ones were sticking out to me like a sore thumb lately.
