No problem I like a good argument ;) The Achilles is probably one of only a bare handful of Forgeworld units I think are over the top (and that doesnt mean there arent over the top units in the normal codexs) What irritates me is that some of the units are just clear improvements on units that are already in the codexs. Most people point to the eldar mini skimmer and call it a straight improvement on the vypre (im not sure I agree but that doesnt matter..) As well many of the army lists can be quite ridiculous and I get that they arent saying the lists are 40K approved but its a dangerous path to start treading IMO. This might come from my background with D&D where by there are too many players that seem to obsess with finding each and every tiny rules interaction that breaks the game and then instead of writing it off as strange or funny they, you know break the game.
