I don't like it it seems like amateur job. For a big video game company I think paying someone to do the job could be a good option to have a personalized and functional theme. Maybe a VBulletin theme contest needs to be done?
I don't like the fact you can't collapse forums anymore on the main page. There are so much forum we don't want to see, now I end up more in NOT looking at the forum I'm interested in because sorting all relevant forums is just boring after two days of use.
I don't like the colors they are all too much to an extreme and do not represent the company but more the current KF 2 color scheme. I'm not against a KF 2 theme (and I think having multiple selectable theme in our profile could be great too..), but I'm all for a more good looking theme so if it is a KF 2 theme let it be better and more KF 2. Having three skins could be good, a TWI grey/yellow one, a KF 2 black/red/orange/ light blue one, a RIsing Storm 2 one. Yeah having three of these would be cool, three good professional looking theme with good functionalities in it like collapsible forums
I don't care the reputation system.
The forced WYSIWYG quick reply thing is not that bad if a more common old style bbcode normal reply function was also here.
It is missing bbcodes buttons. overall the new quick reply box is not intuitive, the most used features are hidden behind buttons.
Uploading pictures is ridiculous you end up with an icon uploaded where you can't see ****.
and so on..
I like the fact that is new forum engine, with newer features and web technologies (having just the content of the page loading instead of the whole page is fun).
