The bane of all open ended games are limits, and the biggest limit in DAoC is level 50. Why does it have to end there?
If XP requirements kept doubling (or more) then why not let characters achieve higher level? So they could get to level 51 with the same effort it took to get another character to level 50. And same again to level 52 taking double effort of a 51.
The fear may be that hard core gamers may become too uber with the ability to achieve extra levels, but I don't think an extra level or two is so much, especially compared to ToA ML, and you can tweak the XP requirements to make it ever more difficult to gain more levels, you would also adjust the XP required to level in the 40s too.
