I've been looking through the UK Released thread, and I found a lot of complaints. I think we should post them here, just so we don't go off topic. Here's mine:
The RefBot just shoves you aside, when he should move around you and isn't the way he should be.

The House Robots come out whenever they bloody well like, and don't always stay in the CPZ, even if they have a red card.

The Flywheel weapons aren't fast enough.

The Pincer weapons should do damage.

You should be able to design your own weapons and chassis. That's what I expected from a PC game. Well, the chassis part anyway.

If you play as the House Robots (using cheats thanks to thepimp), you can see behind Killalot at all. You can't see if his pincers are working, and his lance just goes up and down. WTF's up with that?!

When playing Football in Arcade Mode, the opponent doesn't go for the ball-he goes for you instead! Also, I think Dead Metal should be the goalie, not Killalot. He's too damn big!

When using Dead Metal yourself, you can't see if his pincers have grabbed an opponent, and his saw doesn't move forward!

There are more, those are the only ones that I can think of. Post your complaints here!

I agree with most of those except the "House Robot" one. Since I downloaded the patch, the House Robots stay in their CPZ, and remain there if Red Carded.

Well, i got the game recently, and it has a lot of weak points, though once you get past the first bit (in my case, when i unlocked weely big cheese) it gets fun.
However these are my complaints:
The housebots attack you for no reason, and usually decide the outcome of a fight make you lose a lot

Refbot is just an annoying moron that keeps crashing into you, blocking your way and often slams you out of the arena or in the pit.

For some reason it's either impossible or insanely to get robots on their back, except for dead metal, flip his pincer once or twice and he's upside down (very useful).

Refbot or the house robots often put your opponent back on its wheels wich WILL make piss you off.

Sometimes you'll go flying and spinning out of the field with a slight nudge on the Ship and Rooftops.

The junkyard arena is terrible, you'll end up in the crusher most of the time in the most ridiculous, frustrating and above all impossible ways.

If you leave an arena champion fight, you cannot do it again.

when you use the 36 volt motors you cant control the robot, if you turn, it starts spinning.

Flywheels are too weak, they should be devastating and knock robots out of the way.

Invertible chassis? not entirely; when it gets flipped its barely controllable, it turns for no reason

On the rooftop arena the housebots always try to push you off the roof, especially matilda.

you wont get past the first levels without yelling, swearing and lots of deep breaths.

A lot of these problems are caused by the terrible physics, causing robots not to flip when they should, or even send you flying instead of the robot you flip. (seriously WTF)
I also wonder why they made the housebots so dominant, in AOD they were behaving perfect, so why not now?

The commentary is not really a complaint for me, it migt not make much sense but it does add to the atmosphere.

Then again, despite all these bad sides, believe it or not, once you unlock wheely big cheese the game will give you hours of fun
