I can see from your explanation how these issues could be alleviated for the end-game crowd. While it's understandable that you'd take my meaning to be that, I'm more worried about the soloable content. That has a much higher chance of getting removed either due to game direction (no longer viable, or making such content a joke) or playerbase (in such content all it takes is one troll or 'helper', whatever their intentions the effect is the same under such a system. If I'm low on HP against an enemy, it's not necessarily that I'm losing or need help, it's that it's a tough fight and I want it that way).

While my concerns likely do not reflect the concerns of the majority of the posters here who seem to be MMO veterans, I'm one of those only drawn in the by FF name. Anything that increases the likelihood of trolls in my content makes me that much less likely to keep playing and/or to try that next MMO. I cannot see why solo content and that requiring large groups of people cannot coexist, and what I saw of FF11 that can be done well. It gets me worried when all these so-called improvements I see take this game away from that direction.
