Evan: "And Kruse's battalions all came back as well Paul, unlike the fine British cavalry the Cumberland hussars....
The 5 battalions Nassauers of Saxe-Weimars brigade fought just fine at Waterloo"
No Evan -
1. Kruse's brigade rallied. This was because there was a line of cavalry physically stopping them. Though as Kruse's troops didn't play any more part in the battle it is a rather moot point you make.
2. The Cumberland Hussars were not a British cavalry regiment.
3. That the 5 battalions in Saxe-Weimar's brigade "fought just fine" is perhaps understandable given that they were deployed on the extreme left and saw very little action.
"....not to mention the 3 battalions of experienced British troops that ran at QB when French cavalry broke their squares & took at least one set of colours."
No Evan -
Only one (1) British battalion at Quatre Bras was caught in line and overrun by French cavalry, losing a colour. The battalion was an inexperienced "second" battalion. No British squares were broken. There is a very detailed account in Mike Robinson's 'Battle of Quatre Bras'.

There were no troops "positioned out it in front of the british in exposed positions on the face of the gentle slope" (apart from those KGL inside Le Haie Sainte). (I suspect you might be confused with Bijlandt's brigade - these were Dutch-Belgian, and were pulled back behind the reverse slope about an hour before the battle commenced).
Peoples_Republic: "Wellington also commented that he wished all the british were with him in spain. quite a few were newly form british units. And a few of them did not perform well either."
By "quite a few were newly form [sic] british unit", I think you mean one battalion - the 3/14th Foot, a battalion which included a lot of teenage recruits whose experience was garrison duty in Sicily. Wellington stationed it on the far right and it never saw much action at Waterloo. There were also four relatively inexperienced "second" battalions in Halkett''s brigade, but these were hardly "newly form british unit".
And as to the claim "a few of them did not perfrom [sic] well either", what instances are you refering to? Halkett's brigade (mentioned above) collapsed at the end of the battle, but it had sustained almost 50% casualties by that time.
Peoples_Republic: "I just feel that alot wargames and board games and commentries try to paint a picture of the allies of the british as milita or second rate"
I don't believe anyone would rate the KGL as "second rate"!
But the picture is based on the simple fact that a lot of the allies were Hanoverian Landwehr, Dutch Militia, or recently raised units with a lot of young conscripts.
