It seems lately that everywhere you look online, there are conversations about how epic levels just plain don't work in 4e. Even the ever awesome Penny Arcade are moving over to Pathfinder to try and challenge their players (I'm going to be rather amused to see how this goes, if the "homework vs results" is the same as 3.5 - i.e. many hours DM's work undone by players in 2 rounds), and if I am honest I don't get it!
Ormid and the boys are 18th, nearly 19th level, and are well made, tough characters. I do not have any problems challenging them, and in truth, despite all the powers they will get as epic characters, simply do not envision any kind of issues with challenging them. In truth, I sometimes have to adjust things down in my games, as I realise that I may have gone a bit over the top - maybe it's the old school in me. However, as there seems to be so much talk of 4e being unbalanced and ungodly at epic levels, I think I shall document how things go with my groups when they are there....and possibly start with the upper paragon tier, as that too seems to be outside 4e's "sweet spot".
So, if you are one of those curious about higher level play, please, drop in and have a look see. Make comments, and share your own experiences.
And Gabe, Tycho, good luck guys. I loved 3.0 / 3.5, but I don't miss spending two days crafting an epic level bad guy, only to see them murdered in 2 rounds by a character wielding epic magic and a super optimised character with broken maths.
Good luck, and fair winds!
