Alot of people scream Codex Creep every time a new Codex is announced (even before the rumour mill starts) and sure, some Codex's have been upped a notch, but then every other follows suit. At the end of 4th Ed alot of the Codex's had specific gimmics and their own tricks, Dark Angels had Termie troops, Dark Eldar were fast and fragile, Imperial Guard were slow and shooty and Eldar were Psyker Masters.
With 5th Ed Dark Angels were ousted with Space Wolves getting Termie Troops and now the Grey Knights get them too, Dark Eldar became a bit more survivable (not much) and Guard became Faster, Eldar were pushed off top of the Psykers by Marines. But we are looking at all the 5th Ed Codex's and comparing them to 3rd and 4th Ed Codex's. Which means, we will see all the Codex's get some new gimmic plus strengthen their weakness's, GW seem to be working on everyone having something similar to everyone else, plus a bit more, I am sure this is to partly increase sales and partly to settle the cry of "Codex Creep" but still the Internet Mobs persist until it is their armies turn for the new and shiny.
My general Point therefore is that if you feel cheated, wait your turn, it will happen and then everyone else will moan at you just like you moaned at them.
