50 is a low cap, that and the fact the game has mobs up to level 90ish.

I say they raise it to 75 like in ffxi and leve it there for 8yrs or so. The not making old content worthless I agree with. Content should never be scrapped one of the biggest issues I had in other mainstream mmos, and what I loved in XI had people in sky 8yrs after it was out.
