The thing that pisses me off about roblox even more than the lag, is the lack of original ideas and on-theme builds. The other day I saw a place called "Ben 10 vs pokemon". How on earth does that relate to legos in the slightest way?? It was filled with images mounted to bricks, and completely threw off the game's charm.
Another thing is I hate it when people try to make this little cutesy game into a hard-core shooter; Places based off of call of duty or some other fps.
Also, I think a major reason roblox lags so badly is people load up their place up with so many scripts. The roblox engine wasn't meant to run sixty buggy scripts, on top of a physics engine.
The most fun I had on roblox was at the simpler places, like crossroads. Where it got to the basics of what the game was really supposed to be about: Messing around with physics, hanging out with friends, and racking up a few kills. And those places hardly lagged. Now people don't make places like that anymore.
Until the community sees reality and goes back to what the game was originaly supposed to be about, and stops making places like "get eaten by a giant!!!!" Nine-year-old vorophiles But I just dont see that happening.
