That is a very accurate statement. Its a slaughter house when both of those conditions are met. The lance formation being only on the charge didn't really matter to me, on the charge he would kill half of the unit and then the other half would die to crumble. I don't know if its true or not but someone at the store told me that the newer books are watering down the armies and making them weaker, especially VC. If this is true then I'm at a huge disadvantage. He's using the Bret book from like 1982, if the grail knights toughness is actually only 4 like was said earlier then I think they are watering down armies.
I wouldn't say that's true. Brets are fairly overcosted across the board, and most of the options in their book just plain don't work.
The only reason that Brets still work as well as they do is lance formation, M8, and HKB.
Lance gives them a smaller frontage and greater SCR than their low model count would otherwise prevent. Combined with 2+ saves and the blessing this makes their lances surprisingly durable, and strong against anything with no SCR of its own.
M8 makes them a highly mobile cav army, which are dominant in 8th. They don't have all the tools that other 8th armies have, and the power curve has certainly risen almost across the board since 6th edition in terms of power-per-point. However they're still very strong considering how old their book is.
And finally HKB. The Virtue of Heroism lord is ludicrously effective for his points cost. He's the answer to so many problems that Brets don't otherwise have a solution to, on account of the aforementioned lack of competitive options in their ancient book. Steam tanks? HKB lord. Nurgle prince? HKB lord. K'daii destroyer? HKB lord.
...as I've said though, understand these strengths and the army's inherent weaknesses and they're a strong list but nowhere near as strong as HE/DE/WoC lists are. Brets have little in the way of
chaff or counter-
chaff. They're only truly effective if they catch you with a charge. And if you can survive that charge it's only the characters who are particularly troublesome.
VC are actually a really good matchup against them. So long as they don't blow clean through a unit on the charge you can usually grind them out once their lance bonus and formation go away. We've got lots of
chaff to stop them up. And blender lords slaughter knights like nobody's business. Trouble is that
VC is a very finicky army, especially for new players.
