This thread made baby Jesus cry...
I am not sure that appeals to Jervis, as some looming spectre from the past, is entirely helpful anymore. He is that, simply a spectre, until Fanatic gets back on its feet (probably never) at which point he will probably, with a wave of his hand, destroy much of the hard work done so far anyway...
I dont know how the internal workings of the ERC function, but I can tell you that the sheer amount of stuff floating around is so damn confusing for anyone trying to get into Epic (as I did fairly recently) that people do not know what is what and by who and what has been playtested, being worked on, abandoned, official, unofficial, and any other appropriate adjective. To this end, would it not be an idea to have a disclaimer (on something like this Tyranid list) that it is a variant and the 'official' current playtest list is X and can be found at Y? This would really help new players to discover what is what (especially those that see E&Cs Tyranid list and cry that their old figures cannot be used, never realising that the 'official' list has them all in). If you are serious about 'new blood' (like me ÂÂ

) then anything you can do to help them out is worthwhile, in my most humble opinion.
To get back on topic, personally, I am not so sure it is helpful to include only units that are in 40K in Epic - epic is an army game, not a skirmish game (40k), and so will have units not represented in 40k. Following that route, until the release of apocalypse we would not have had super-heavies in any epic army (and these things were taken from Epic in the first place) and (if I am not mistaken) there are units even now that we would not have following this philosophy (SM Landing Craft? Many many units from the LaTD list?). Conversely, I dont think Baneblades, Stompas, etc... are approriate to 40k either, unless you are playing on a football field (but appreciate that is just an opinion...).
As for your document, if you will permit me E&C: I perfer your slightly toned down Harridan (with only 1 MW attack), but at the moment it is sort of bouncing around on the floor like a downed moth, beating its wings in a futile attempt to fly as you forgot to add 'skimmer' to it.
